OL is the only position I know from experience having played it. Alabama's problem is mostly coaching. Yes they have to be big, strong, and have good feet. But It's extremely technical, almost like having to know kung fu or something to be able to manipulate or move your guy. You don't necessarily have to blow him off the ball every play but if you looked last night they (Indiana) just walled off our DL, On running downs they looked like a choreographed swimming team. It was almost flawless. If we got anything going it was on a few pass rushes which are a little more unpredictable. You get that from guys who have played together every week and have been taught the right technique. it doesn't happen overnight, it can't be made to happen over night. Then sometimes you have to bow up and knock someone off the ball and once again Indiana could do that when they had to . That just requires a little meanness. Big guys are often often overgrown teddy bears. Who ever picked on them growing up? Nobody, Teddy Bears. Every so often you run across some dude who got skull dragged around his neighborhood by the psychopath teenager down the street who would end up in prison later. He just licks his wounds and takes it but later on hits a growth spurt and goes out for football and spends his career making everyone pay for the pain he suffered as a child.
Alabama rotated guys more than I've EVER seen at any level. Yes 2 guys can somewhat share a position early but by game 4 or so you got to pick the best 5 and go with it. Otherwise they are never going to be tight enough.
Alabama absolutely has no physicality, they ain't mean, they don't get excited. teddy bears.
I can't determine any specific technique being employed unless they are trying to zone block which at the college level must means brain injury for your backfield.
How to fix it? First fire the OL coach, I'm sure he's a nice guy, sorry, life sux.
Second find someone who has a great running game from a winning program and throw whatever money is necessary to the OL coach to hire him. I for one believe the entire team revolves around the OL. If that ain't right joe montana under center won't help. I would have no problem paying my OL coach second only to the head coach. it's that important.
Third in the portal find the meanest nastiest most awful OL you can find, someone who is so mean he will effect everyone around him. Someone who will literally eat teddy bears, these guys don't need another buddy they need a leader they fear. Once again if that requires money, find the money. but someone has to be the catalyst.
Do all that and by about game 5 next season we should start to see SOME improvement. But this is really going to take another full season or season and a half to fix IF WE STARTED TODAY.
Or we can do nothing and get skull dragged around by all the good teams like we did under Shula. Their choice.
