As we lead up to 2020 Philadelphia Eagles training camp, we've been taking a look at every player on the roster, and how they fit with the team, assuming, you know, there is a camp and a season.
Training camp previews
Today we'll look at the cornerbacks, a position the Eagles feel they have upgraded this offseason.
| CB | 1 | 2 | 3 | 4 |
| CB | Darius Slay | Sidney Jones | Prince Smith | Michael Jacquet |
| CB | Avonte Maddox | Rasul Douglas | Tremon Smith | |
| Slot CB | Nickell Robey-Coleman | Cre'Von LeBlanc | Grayland Arnold |
Darius Slay
Back in May, we took a detailed look at Slay's 2019 season with the Lions, in which we found every time he was targeted. This required watching every defensive snap in 14 Lions games, which, was time consuming and not super fun, ha.
We cut up those targets into a video, and gave analysis of each game. In case you missed that, I think it's worth checking out.
The most important takeaway from that exercise was that if Slay doesn't experience some sort of falloff, he's going to be the best cover corner the team has had since Asante Samuel.
In 2019, Slay almost always followed the best receiver on the opposing offense. He was tasked with covering receivers who are big, small, fast, strong, and everything in between, and he did so both outside and from the slot. In our analysis, we differentiated between the targets when he was in zone coverage and the ones when he was in man. Obviously, zone coverage is part of the game, but the corners who separate themselves from the rest of the pack are the guys who can man up and take away a receiver. Here's how he fared:
| Darius Slay | Comp-Att | Yards | TD-INT | Rating |
| Zone | 10-12 (83.3%) | 121 | 0-0 | 108.9 |
| Man | 29-65 (44.6%) | 462 | 3-2 | 71.4 |
| TOTAL | 39-77 (50.6%) | 583 | 3-2 | 78.0 |
Some sites have Slay with as many as 90 or so targets faced on the season. The guess here is that they counted anything near him in zone coverage. Obviously, a lot of that is subjective, but I was not as quick to call some passes in the vicinity of Slay "targets."
What is not nearly as subjective were his targets when in man coverage. How did he fare against each individual receiver when in man coverage? Here are those numbers, sorted by QB rating:
| Darius Slay | Comp-Att | Yards | TD-INT | Rating |
| Allen Lazard | 2-2 | 46 | 1-0 | 158.3 |
| Adam Thielen | 1-2 | 25 | 1-0 | 135.4 |
| Stefon Diggs | 5-7 | 100 | 0-0 | 113.7 |
| Davante Adams | 4-7 | 63 | 0-0 | 87.2 |
| Allen Robinson | 3-7 | 49 | 1-1 | 67.0 |
| Courtland Sutton | 3-7 | 23 | 0-0 | 51.5 |
| Amari Cooper | 2-6 | 31 | 0-0 | 51.4 |
| Terry McLaurin | 3-10 | 42 | 0-0 | 44.6 |
| Keenan Allen | 6-11 | 83 | 0-1 | 41.1 |
| Damiere Byrd | 0-1 | 0 | 0-0 | 39.6 |
| Larry Fitzgerald | 0-1 | 0 | 0-0 | 39.6 |
| Geronimo Allison | 0-1 | 0 | 0-0 | 39.6 |
| Jake Kumerow | 0-1 | 0 | 0-0 | 39.6 |
| Tavon Austin | 0-1 | 0 | 0-0 | 39.6 |
| Marquez Valdez-Scantling | 0-1 | 0 | 0-0 | 39.6 |
| TOTAL | 29-65 | 462 | 3-2 | 71.4 |
Again, for more context on each of the above matchups, go check out the deeper analysis in the post from May, but I guess the point to be made here is that allowing a passer rating of just 71.4 when you're trailing the opposing offense's best receiver all day (and he faced a lot of really good ones), while playing behind one of the worst pass rushes in the NFL, is pretty impressive.
Compare No. 1 receivers vs. Slay, and No. 1 receivers vs. Eagles corners last season, and it's no contest. In 2019, No. 1 receivers abused the Eagles' secondary. A sampling:
| Player | Catches | Yards | YPC | TD |
| Terry McLaurin, Washington | 5 | 125 | 25.0 | 1 |
| Julio Jones, Falcons | 5 | 106 | 21.2 | 2 |
| Marvin Jones, Lions | 6 | 101 | 16.8 | 1 |
| Devante Adams, Packers | 10 | 180 | 18.0 | 0 |
| Stefon Diggs, Vikings | 7 | 167 | 23.9 | 3 |
| Amari Cooper, Cowboys | 5 | 106 | 21.2 | 0 |
| DaVante Parker, Dolphins | 7 | 159 | 22.7 | 2 |
| Darius Slayton, Giants | 5 | 154 | 30.8 | 2 |
| Terry McLaurin, Washington | 5 | 130 | 26.1 | 1 |
| DK Metcalf, Seahawks | 7 | 160 | 22.9 | 1 |
Slay will improve on that awfulness drastically, as long as he can stay healthy, and assuming Jim Schwartz will allow him to shadow the opposing offense's best receiver.
Overall, Slay is at his best when he's playing tight man coverage, as his mirroring and matching skills are some of the best in the NFL. He does not give up much separation, and his ball skills are excellent. In fact, he has more pass breakups than any player in the NFL since 2015.
| Player | Pass breakups (2015-2019) |
| Darius Slay | 82 |
| Stephon Gilmore | 79 |
| Marcus Peters | 77 |
| Janoris Jenkins | 73 |
| Johnathan Joseph | 66 |
If there's one thing to knock about Slay's game, it's his abysmal tackling, or perhaps better stated, his abysmal effort when tackling. It should be noted that Slay was made aware that the Lions were not going to pay him, which perhaps contributed to that season-long lack of effort when tackling. That's certainly not a great excuse, but the Eagles believe that a happy Slay, on a more competitive team, will be a more interested tackler.
Avonte Maddox
Maddox is a very athletic player, but the challenge for him at outside corner will be his lack of length. Not only is he only 5'9, but he also has very short 29 1/2" arms. A look at his athleticism and size measurables:
Maddox has proven to be a versatile defender for the Eagles in his first two seasons in the NFL, starting games at outside corner, slot corner, and safety. In my view, his profile / skill set fit those positions best in the following order:
- Slot corner
- Safety
- Outside corner
However, the team has two slot corners in Nickell Robey-Coleman and Cre'Von LeBlanc. They also have a pair of starters in Jalen Mills and Rodney McLeod at safety, to go along with offseason acquisitions such as rookie fourth-round pick K'Von Wallace and free agent Will Parks.
As such, an argument could be made that Maddox's versatility is going to waste if he's solely going to be an outside corner. I'll respectfully disagree there, to some degree. Get used to the term "positionless," as it applies to Eagles defensive backs, as the Eagles want their secondary to be comprised of players who can play every position. Maddox certainly fits that profile, but I would expect opposing offenses to attempt to create matchups against him with big receivers.
Nickell Robey-Coleman
Sidney Jones
Like we did with Slay and Maddox above, we looked at all of Jones' targets on the 2019 season. While he had a couple of clutch pass breakups in wins over the Giants and Cowboys, his season otherwise was shaky, at best, both in terms of his play on the field, and continued durability concerns.
Jones obviously missed almost the entirety of the 2017 season while recovering from an Achilles tear. That was expected, of course, but he has also missed games both in 2018 and 2019 because of soft tissue injuries. He has not been able to do whatever has been necessary to stay on the field.
In the Eagles' loss to the Seahawks in the playoffs, a healthy Jones did not play a single defensive snap, despite his late-game, late-season heroics. Why?
What really likely got Maddox in Schwartz's doghouse was the Eagles' game against the Vikings, in which a struggling Jones took himself out of the game for a crucial series, and his replacement gave up a touchdown. By contrast, in the Packers game, Maddox was laying on the field after taking a shot from Andrew Sendejo that could have paralyzed him, and it's shown in "All or Nothing" that he was lobbying to trainers to let him continue playing.
The week after the Vikings game, the starters in Dallas were Mills (returned from PUP), Rasul Douglas (who was destroyed worse than Jones in Minny), and Orlando Scandrick (signed off the street a few weeks prior).
Schwartz at times can live with poor play on the field, as we have seen, but he has shown that if he does not trust your mentality, you won't play, right or wrong.
Cre'Von LeBlanc
LeBlanc started at slot corner against the Seahawks in the playoffs, and while he didn't have a good game, it revealed that Schwartz preferred him on the field over Jones and Douglas.
LeBlanc is a scrappy, confident corner who has the mental makeup Schwartz likes, and he has mostly filled in ably when his number has been called. However, on the Eagles' roster in 2020, he is probably just a backup slot corner to Robey-Coleman.
Rasul Douglas
Because Douglas received a "Proven Performance Escalator" bonus (for accumulating playing time benchmarks), he was scheduled to count for $2,309,572 against the cap in 2020. There was no way the Eagles were going to keep a sixth cornerback on their roster at that number, so a trade or release of Douglas felt like a strong possibility. Instead, Douglas agreed to lower his salary to $825,000 to stay in Philly.
Douglas does have some traits. He has great size, he's a physical tackler, and he has some ball skills, but he simply can't run with fast receivers, as he was exposed repeatedly on deep balls in 2019. Maybe his size might make him appealing to teams running schemes that can mask his speed deficiencies, and he could still be had in a player-for-player trade?
I wouldn't rule that possibility out.
Grayland Arnold
The Eagles had a draftable grade on Arnold, but they were able to scoop him up as an undrafted free agent. Arnold had six INTs for Baylor in 2019, most of which were in big games, and he offers some added value as a punt returner. He has a fun highlight reel.
Arnold felt like a decent bet to crack the 53-man roster, at least compared to the other Eagles UDFAs, but a shortened offseason will hurt his chances. He's a smaller DB at 5'10, 187, who projects to either slot corner or safety in the pros.
Tremon Smith
Smith was a sixth-round draft pick of the Chiefs in 2018, where he played in 14 games as a rookie, starting one. He was also the Chiefs' primary kick returner, and the Chiefs even tinkered with him at running back. They cut him the following season, and he was on and off the Packers' roster throughout the season in 2019, before the Eagles signed him to their practice squad in December.
Here he is returning a kick 97 yards against the Patriots his rookie season:
Prince Smith
UDFA longshot. He does have intriguing strength, and was a four-year starter at New Hampshire. BLG did some legwork on him.
Michael Jacquet
Another UDFA longshot. Jacquet has good size, and he converted from wide receiver to corner at ULL, but with little time to impress the staff, his best bet is the practice squad. Again, BLG did some legwork on him.
