You can't fix what is wrong in one week. As far as the offensive is concerned, not in one or even two off-seasons either. We are 1.5 years into a four year rebuilding project on offense. Two years to recruit enough linemen to populate a two deep and begin developing them. Two more years to get them the experience they need to succeed and build depth for the future. There are other challenges. Luckily, Franklin has proven he can recruit running backs, but we need another QB with the skillset to run the offense. Allar is the path to the future but we have no player behind him if CV hits the portal as most expect and Smolik decommits. Pribula will never play a down at QB. If he does, it will look like last year's Iowa game with Roberson. Beyond the line and potential QB problems, we still need to find a legitimate #1 receiver.
Defensively, I wouldn't have hired Manny Diaz. Our defensive problems are entirely of our own making. Look at what Kirby Smart has done. Look at what John Harbaugh has done since his time at Stanford. Their defenses aren't wed to a fixed system like ours is. The right coordinator could turn around the front seven in an offseason with the talent that is here. There is a reason why most of our ends play outside linebacker in the NFL. Ellies and Izzard both demonstrated they could hold up against the run last year after PJ went down. Start there. I posted this in another thread. Go with a two gap scheme which allows you to move back and forth between an even and odd front based on talent. It is what Bama, Georgia and Michigan all do. It is what USC did under Pete Carroll. Notre Dame did it under Lou Holtz. Heck, Diaz could make two changes right now that would yield some results. Move Beamon to 5 tech, slide Izzard into the 3.
