You're all crazy.
If you could have your most talented group be the DL, secondary, or LBs, what would you pick?
I'd pick linebackers, followed probably by secondary and then by DL. That isn't to say you don't need a good DL, but my god they can be taken out of the game so easily by quick passes, slants, screens, etc. So yes, we have a great DL, but they can be neutralized pretty easily.
Shafer has run 4 man fronts, 3 man fronts, man to man, zone. He's tried damn near everything. If NOTHING is working, I have a hard time believing that it is scheme. He seems to put people in the right places but players give up contain, bite on the first (fake) handoff, and let their guys beat them in man to man. No one could coach this defense very well. It doesn't help either that the offense sucks. That isn't the reason, but nothing is helping.
How can it be shafers fault that players blatanly miss tackles, and every time they make contact with a player there are about 3-5 YACs. Put that on the position coaches.
Oh, and you know this is not shafer's preferred defense. The 3-3-5 is something RR likes...a lot. Why don't you go bitch at him. Shafer tried it, because nothing he wanted to do was clicking for the players. I guess this didn't either. We have sucky players at the most important positions.
Go make Christmas plans with the family, we aren't going to a bowl game. Get over it!
