Why have Louisiana FBS schools struggled so much at QB lately?

This past Saturday wasn't just an abysmal performance for the LSU offense. Three of the five Louisiana FBS schools struggled, particularly at the QB position, on their way to three embarrassing losses. Of course we are all familiar with what happened with LSU. Tulane, who has struggled for years now with poor QB play had the worst performance of all Saturday. QB Glen Cuielette threw two pick sixes and had a fumble recovered for a TD en route to a 37-6 loss to a 5-4 UCF team. ULL QB Anthony Jennings went 17-30 with 0 TDs and ULL lost 23-13 to an Idaho team that gives up an average of 33.3 points per game. While La Tech and ULM both had good days it still seems to me like given all the talent LA produces, these major in-state programs shouldn't struggle as much as they do (and so consistently) at such an important position. Does LA just not produce good QBs? And if you believe so what is your theory on why?
