Bennie Logan set new career highs for the Eagles in 2016 with 2.5 sacks and two forced fumbles, although clearly the bar was low in those particular categories. But while the four-year veteran maybe made a few more big plays than in years past, he was less active overall after making the switch from the nose tackle in a 3-4 scheme to a defensive tackle in a wide-nine, 4-3 alignment.
After racking up at least 55 tackles in his first full two seasons as a starter, Logan managed only 24 in his new role. And while he doubled his quarterback hits from three over 2014-15 to six, his tackles for loss were cut almost in half, from eight, then nine, to five.
Logan did miss three games with a hip injury, which who knows how that might've affected him over the final eight games. In the four contests prior to getting hurt, he already had 2.0 sacks, a forced fumble, three quarterback hits and three tackles for loss, so there was a marked difference in impact beforehand.
Regardless, that must make it difficult for the Eagles to evaluate his performance, which is kind of a problem, because Logan is due to become a free agent. How does the front office go about determining his value in this defense?
It's not an easy question, and the first thing you have to ask is who takes Logan's place in the starting lineup? In terms of an in-house replacement, the individual numbers don't indicate a huge drop-off with Beau Allen. Allen only recorded a 0.5 sack and failed to force a fumble in '16, but finished with five more tackles, the same number of tackles for loss and one less quarterback hit than Logan in 55 fewer snaps.
The Eagles would need to address depth at the position if they went with Allen, but that path wouldn't necessarily cost as much money as retaining Logan. A proven disruptor up the middle — especially in the right scheme — can command a lot on the open market.
Take a look at the contract fellow LSU product Michael Brockers got from the Rams back in September. Brockers received a three-year extension worth over $33 million with $18 million guaranteed. Granted, a lot of that is tied to a roster bonus he doesn't seem poised to be with the club to earn in 2017, but even just his salary for last season totalled nearly $7 million.
That was coming off a season in which Brockers posted 44 tackles, 3.0 sacks, zero forced fumbles, eight tackles for loss and six quarterback hits. Those are a step up from Logan's totals in '16, but not necessarily better than some of his previous campaigns.
Again, it's difficult to determine Logan's exact value, but to the right team, he could certainly be worth upwards of $5-6 million per year. Tough to say whether the Eagles would be willing to go there, especially given their tight cap situation.
DEFENSIVE TACKLES UNDER CONTRACT
Cap Number: $9,400,000
Cox probably didn't live up to the expectations that come with a contract worth $100 million — the second-highest total for his position — but he's still one of the most dominant interior linemen in the league. The five-year veteran better get used to the fact that he's going to face constant double-teams the next few years, because the Eagles don't have a pure pass-rush specialist on the edge who can take over games. With that in mind, 6.5 sacks and 14 quarterback hits probably aren't enough from Cox, although when he's at his best, he can carry the Eagles to victory. Just look at his first three games of the season, all wins: 11 tackles, two tackles for loss, 3.0 sacks, four quarterback hits and a forced fumble. Either way, $63 million in guarantees says he isn't going anywhere for awhile.
Cap Number: $705,562
Allen proved to a perfectly serviceable rotational player in 2016, plus added another position to his resume. He can play fullback in a pinch, which is impressive in itself for a 327-pound man. Hard to say whether Allen is starter material. According to Pro Football Focus, Logan still charted better against the run among qualifying interior linemen — although Allen was above average — but the Wisconsin product was the more productive of the two when it came to rushing the passer. If the goal here is primarily to save money, the Eagles should be able to get away with Allen and a cheaper veteran or early draft pick aside of Cox, who makes sure everybody else across the line is getting one-on-one treatment anyway.
Cap Number: $690,000
Not going to lie, I was a little surprised to see Hart is still on the roster. Depth issues led to the Eagles bringing him back, although he never suited up. The former fifth-round draft pick has now been active for a grand total of 15 games in three seasons. Scouting reports suggested Hart would be better off in a 3-4 alignment, but even that is suspect at this point.
Cap Number: $540,000
An undrafted rookie out of Washington State, Vaeao had his moments. His strip-sack against the Bears in Week 2 was a big play, and he got the quarterback again in the first meeting against the Giants. Otherwise, Vaeao was pretty quiet. He figures to be competing for his spot on the roster in 2017, although if Logan leaves, it might be difficult finding enough bodies to rendering a prospect with a full season's worth of experience expendable.
Shittu had a standout preseason, racking up six tackles, 1.5 sacks, three tackles for loss and three quarterback hits. That was enough to land the undrafted rookie out of Standford on the Eagles practice squad, though it might be telling that they liked Vaeao and even Hart more. Nonetheless, Shittu signed a futures contract at the conclusion of the season and will be an interesting name to keep an eye on come training camp.
2016 Cap Number: $1,842,023
To be fair, Logan probably made more of an impact than the numbers indicate. The Eagles' wide-nine just doesn't feel like the ideal fit. A case could be made Logan was transforming into arguably the best nose tackle in the NFL prior to the switch. Filling a gap and building a wall at the line of scrimmage seem to be his strengths, not so much getting upfiekd and attacking quarterbacks. Again, we'll allow for the possibility Logan wasn't 100 percent all season, and he could certainly continue to develop with more experience in this role. If it were my money, it would be all about price. If we're talking the lower end of the spectrum, maybe $4.5 million, it's easy to justify bringing him back. Once that price tag soars — and it certainly may — it simply may not make much sense for the Eagles anymore.
