Louisiana Tech is staying home because their AD screwed up royally.
While I agree that the AD should have taken the Indy Bowl, the Bowl system itself is at fault as well for relegating that shitty bowl to LaTech in the first place. They should have had better options.
The entire bowl system needs to be fixed. Going to a playoff is not going to solve the problem for those teams that don't make the playoffs... they deserve to have exhibition games against evenly matched quality opponents, games people want to see.
