During Marrone's rookie season in 2009, he showed us on quite a few occasions how raw he was with regard to game management and how much improvement he needed to make. I chalked it up as rookie mistakes and he would learn from them and become better the more experience he acquired.
My concern now is that he's not learning from his mistakes...possibly because he's not aware of them.
For example - is there anyone on the staff to tell him that calling a timeout inside your opponent's 15 immediately after a QB scramble with (approx) 1:30 left in the half and :30 on the play clock is a horrible decision? Or is he only focused on his players' mistakes?
