The coaches can't make the tackles or the throws out there (they do both of those things in practice on a consistent basis).
No, but they are responsible for putting the best players on the field. They are responsible for talent evaluation. When year after year you keep seeing guys who can't tackle, can't read plays, etc, that is more so an indicator of poor coaching. Whether the guy just isn't SEC caliber, or whatever, that comes back to the coaches. Blaming Tuberville for anything that happened this year or last year is just as stupid as blaming Shula for Alabama's 3 loss season in 2010. Alabama replaced basically the entire defense (lost guys like Arenas, Cody, McClain, etc) in that year and still only managed to lose 3 games by a combined 18 points. While some are quick to blame Tuberville, what they don't realize is, Chizik seems to be doing the same thing. The only difference is you see more stars on the front end when these kids commit nowadays.
Having a young, inexperienced, but talented team means missing an assignment here and there. You bit on a play action when you really shouldn't have. You released a receiver to the wrong side. You got burned on a double move. You just don't know how to finish that big game and fall a little short. It isn't getting ass raped by your rivals, or getting ass raped by.....MSU while looking totally inept in the process. I'm not trying to be a goat fucking Alabama fan by saying that, it's just the truth. Something has to give somewhere. If these guys just aren't motivated to play to their talent level, or just aren't as talented as first evaluated, it goes back to the coaches either way.
You talk the same way the Shula knob-slobbers always talked, and that's a scary road to go down. "Wait until next year...." was always the party line. Auburn isn't known for shitty football, but people like you are saying it's OK. That's the same line of thinking that allowed Alabama to get completely owned by you guys for 6 years. You guys are slowly slipping into what Alabama was under Shula. Even as an Alabama fan, I don't want to see that happen.
