T nailed it.What we have is questionable schemes and game management for the talent on the roster. The OL starters Thomas, Gillie, Harrington and Jackson are all Napier recruits. The freshman center is a Desormeaux recruit. Unfortunately, neither tackle is very good. Unless they upgrade through the portal, they will be relying on young redshirt sophomores. If you can't pass defend against quicker fronts, you either change your scheme, coach up the linemen you have or go to the portal to improve immediately.
The Defensive Line was leading the SBC in sacks earlier in the season. Lawson, Whitfield, Guidry and Grant are all Napier recruits and good players when used correctly. When they pressured Watson in the first half with 4, he was not accurate. For some reason after tying the game late Morgan goes back to a Nickle or Dime package, rushing 3 DL and two of them are 240 pounds with no push up the middle. Again, is it the talent or the scheme?
The same thing with the interior, Wiser, Narcisse, McGriff, Hazard and Miller aren't bad players. Hazard is a true noise tackle. That is what he does best playing over the center. He is not the same player when he is asked to do something else.
I see a ton of Napier recruits playing and aren't being used at times in the right scheme. So, either change your scheme to fit your personnel, Coach them up and use them in the right packages or recruit to a different system.
Bottomline, it's up to the HC and his staff to fix it. There is no other way around it, if you aren't winning and your players aren't improving then it's the coach. If you don't have the players to fit your scheme, then it's the coach as well. Either way, it falls on the HC and his staff. Fix it!
