Alabama has a multitude of issues keeping it from running the football effectively. One of them is not giving enough carries to the right RB.
I'm far from an X's and O's expert when it comes to football. For that, I defer to those who are. One of the guys who is an expert is Brooks Austin, AKA The Film Guy on YouTube.
He took the time this week to break down the film of Alabama's run game against LSU. Austin explains things so anyone watching can understand.
