That's exactly the issue. You nailed it. It's who's in charge of recruiting (HS and portal) and making sure they are bringing the type of athletes in who are capable of playing vs USC, Indiana, OSU, etc? To me, that's BB. He ultimately makes the call.
I also agree that it's not 1 guy who can bring down a defensive scheme. It's all 11. Outside of Jacas, we don't have the talent to perform at an elite level. We don't. You don't have corners who are capable of playing man in press coverage. You don't have safeties that are athletic enough to properly pick up a receiver who's been handed off by a corner in a zone scheme. Those types of players aren't on the roster.
Layer two to this is the our expectations have been risen. This defense will handle Purdue, NW, Rutgers, etc. That was our baseline. 7-5 would have been a phenomenal season. Now, we're talking about wanting 10 win seasons. That means you're pretty much running the schedule and you're going to get the best shot from teams like Indiana and OSU. These are no longer trap games to the powerhouses.
OSU is going to come in and we're going to get their best shot. Knowing that, what scheme could you or ANY defensive coordinator on the planet come up with when there's a talent differential of this magnitude?
The ONLY thing that Henry can do to keep Indiana from happening again is to continue to do what he's doing and eliminate big plays. We beat USC because of that philosophy. They were going to score, just don't do it in 45 seconds. Make them run 9, 10, 11 plays, eat up clock and shorten the game.
You'll have to ask the insiders who's truly in charge of handing out scholarships. If Henry is solely in charge of making those calls for the defense, then this is his problem. If not....as a staff they need to be better.
