For the first three weeks of the season, Gators Wire has focused exclusively on the Florida offense while reviewing Pro Football Focus grades. Now it’s time to delve into the world of defense and analyze how Florida’s defense performed against Mississippi State.
The big picture isn’t good here. Florida’s defense has been an obvious weak point all season, and the Bulldogs delivered their best rushing performance of the year against the Gators on Saturday.
To determine what’s wrong, Gators Wire is breaking the defense into two groups: the front seven, composed of defensive linemen, edge rushers, and linebackers, and the secondary (cornerbacks and safeties).
Let’s get into it.
Understanding PFF grades
The grading scale ranges from minus-2 to plus-2 with increments of 0.5, and players are given a grade on every play they are on the field for. A zero grade means a player did his job, while the two ends of the scale represent extreme success or failure — think red zone interception at the end of a game or a game-winning touchdown pass when applying it to quarterbacks.
There’s a level of subjectivity to it, but each grade is reviewed at least once. Once all plus-minus grades are in, the numbers are converted to a 0-100 scale to easily compare players. There are some loosely defined tiers within the system — 90-100 is elite, 85-89 is Pro Bowl level for NFL players, 70 to 84 is a starter and 60-69 is a backup. Anything 59 and below is considered a replaceable talent.
Since we’re looking at college athletes with a system designed for the pros, we will consider anything above 65.0 as a solid performance.
Defensive Linemen
We begin with the guys up front, the defensive linemen.
With edge rushers in a separate group, the focus here will be on the run defense, which we know was not great for Florida as a team despite a decent 70.3 grade. But should the blame be on the big men in the trenches? Not entirely, according to Pro Football Focus.
Six different linemen played 17 or more snaps at tackle for Florida on Saturday. Caleb Banks got the start at the left tackle position, taking 33 snaps per PFF. Kelby Collins (29) and Brien Taylor Jr. (17) followed Banks on the depth chart.
Cam’Ron Jackson was the team’s other starting tackle (right). He took 35 snaps to backup Desmond Watson’s 27, and D’Antre Robinson is listed as a nose tackle with 17 snaps.
Taylor and Collins earned the highest overall defensive grades in this group, with 73.4 and 72.4, respectively. Taylor was the team’s best lineman against the run (71.2) and Collins was decent as well (68.8), good for fifth and sixth this week across the entire defense. Collins stood out against the pass (67.4), too. Both were solid tacklers — Collins at 75.7 and Taylor at 74.1.
The starters — Banks and Jackson — earned mediocre defensive grades of 63.1 and 66.4, respectively. A missed tackle from Banks knocked him below our 65.0 threshold for a solid performance, and Jackson played just above replacement level despite posting the unit’s best tackling grade (75.9).
Watson finished between the two starters with a 63.8 overall defensive grade. He didn’t have any tackling opportunities. Robinson posted the unit’s worst overall grade at 52.7, largely due to a poor performance against the run (53.3). A 72.4 tackling grade is the lone bright spot on his line.
Edge Rushers
The edge rushers serve many roles in Florida’s defense. Some are pass-rush specialists, others are better at dropping into coverage and most are good at getting into the backfield.
Pro Football Focus listed eight Gators as EDGE guys against Mississippi State, a combination of defensive ends and outside linebackers.
Defensive Ends
Florida’s two starting ends were Kamran James (39 snaps) and Tyreak Sapp (40), with Justus Boone (19) backing up James.
Boone was actually the highest-graded of the trio at 67.7, largely due to a unit-high 74.7 pass-rush grade. That number was good for No. 2 overall on the team this week, as were his two pressures.
Despite leading the team with three pressures, James finished the day with a 59.8 overall grade on defense. Missing a tackle has something to do with that, but he performed at a replacement level across all phases (62.7 run defense, 55.2 pass rush and 42.0 tackling).
Sapp also struggled in the tackling game, missing two and ending the day with a 26.2 tackling grade. Considering that low number, a 65.1 overall grade on defense is somewhat impressive. He was better against the run (68.1) than the pass (58.6), which is a shift from his performances in the first two weeks of the season.
Outside Linebackers
T.J. Searcy started at left outside linebacker for Florida and played 34 snaps, followed by Jack Pyburn’s 25 and true freshman LJ McCray’s 21 snaps.
This group is less about getting after the quarterback and more about containing, which is reflected in PFF’s grades.
Searcy was the highest-graded edge player on the team with a 68.0 overall on defense. A 79.2 tackling grade puts him in the top three this week, and his 71.7 against the run is the highest figure in the edge room this week. He even was solid (63.7) dropping back into coverage, albeit only on five plays.
Many believe that McCray should get more snaps than Pyburn, but the numbers explain why Florida doesn’t give the true freshman more snaps. McCray is a good tackler (71.1) but the rest of his grades are below 60, which is replacement level. Meanwhile, Pyburn graded out as the third-best player in the edge room (67.4) and the second-best pass rusher (64.5).
At right outside linebacker, George Gumbs played the majority of the snaps. Aaron Chiles on played nine snaps as his backup, while Gumbs was on the field 36 times.
Chiles finished with a higher overall grade (64.3 to 63.3), but Gumbs was the front seven’s best tackler (79.3). That one-point difference isn’t going to send Gumbs down the depth chart. It wasn’t a great day for Gumbs as a pass rusher (54.2), but
Inside Linebackers
The inside linebackers are a bit different from the rest of the front seven because they drop back into coverage more often.
Shemar James and Grayson Howard are the two starters. Both can be on the field at the same time, but it’s James who gets the most snaps by far with 66 to Howard’s 43.
Unfortunately, this was James’ worst week of the season, grading out at 60.4 overall. Three missed tackles is concerning considering he only missed three tackles over 368 snaps as a freshman and six over nine games last season. James is supposed to be the leader of the front seven, and this kind of performance helps explain why Mississippi State was able to run so effectively.
Howard, on the other hand, earned the highest grade of the week (75.4) and posted the highest run-defense grade (77.7) as well. He was also a top-four pass rusher (69.2) on the team this week and was solid in coverage (63.0) over 20 dropbacks.
Jaden Robinson was the team’s primary backup to both starters at linebacker, and he finished just behind Howard with a 73.5 defensive grade. Strong numbers against the run (75.1) and as a tackler (77.6) are very encouraging, and he was the team’s best coverage linebacker (65.1).
It’s good to see Howard and Robinson step up during a week where James struggled, but Florida will need James to pick things up moving forward. The schedule only gets tougher from here, and UCF features an elite running back.
Derek Wingo (14 snaps) and Myles Graham (11) were the other two linebackers to see the field. PFF lists Graham as a weak-side linebacker, but it’s hard to make a fair judgment on him over just 11 plays. The same goes for Wingo. Both finished the day with decent defensive grades between 64.0 and 66.0.
