Shortening pre-season, no concern this would lead to more injuries? In MY view injuries happen as much from inexperence as they do the physicality of the game.
I don't see how it will add to the competitiveness of the games. It's one more week for a weaker team to build injuries for the one week delayed statistical mismatch.
Adding four more teams I THINK will increase costs. By this time of year, most of those fan bases I would predict to have moved on so revenue down also. The weather week 11 is not really condusive to the casual fan or maybe to getting people to man the events. Might put more money into the AD's, Asst AD's and whoever else gets paid per game but for some programs, I think that hits the school's bottom line. I can see why AD's would vote for this but not responsible school or board leadership.
The only ways I can think of to reduce first round travel costs is smaller regions or reseeding the original eight based upon locality instead of a strict 1-8, 2-7....
