Re: Lupoi as Def play-caller, this is from an article someone posted yesterday.
"After some early struggles during the season, Saban stripped Lupoi of defensive play-calling responsibilities and handed them over to co-defensive coordinator Pete Golding, according to sources. Saban had poached Golding from UT-San Antonio in the offseason in part to alleviate concerns about Lupoi’s inexperience with the secondary and as a play-caller. Still, word is Lupoi seemed overwhelmed during practices and didn’t totally grasp situational play-calling. While he was still heavily involved in the defensive game-planning, there was no question Golding taking over play-calling represented a demotion of sorts for Lupoi barely into the start of his defensive coordinator stint."
