It wasn't just one thing with Woodson... the kid just couldn't stay on track. Barring an unforeseen pardon, a couple others will soon be following. The margin or error ain't what it used to be. Be good, or be gone.
As for 'on the field' type stuff... Saban finally has the team stocked, and there is a brand spanking new crystal football in the football complex right now... that kinda raises the bar for everyone on the team. If a player, or player(s), are just there for the ride along, they too will be *cough* encouraged to move along. This ain't 2007 anymore.
