1) The NCAA CLEARLY gives a hoot about academics. It's why no bowl games or D-1 basketball games are scheduled during exams. Didn't you wonder last season why the team doesn't play any games between Dec 5 and Dec 14th? That's the exam period. BC not all schools are on the same schedule, you'll end up with much wider period where no games can be scheduled. In fact, its the NCAAs stated goal to “to manage academics by working to schedule bowl games no sooner than the third weekend in December.” There you go, at the earliest you'd start a bowl the third weekend in December (meaning the earliest you would start would be around the 16th or 17th).
I guess you could have a round of 32 then, a round of 16 around xmas, a round of 8 on NYD/NYE, semis on Jan 8, and finals on Jan 15. Seems too stretched out to be feasible imo, especially when factoring in competition with NFL playoffs.
I wasn't talking about logistics in terms of location, but instead in terms of time management.
I was speaking more before there's no chance low ranked teams get a shot to play. It's possible there is a 16 or 20 team playoff, but I think given the beating football puts on a college players body they won't want to extend the season that long. FCS schools don't have to contend with that as much bc their players are slower, softer, and weaker.
EDIT: Also logistics will come into play under your proposal. If you are using NFL stadiums you are going to have to work around their schedule. Some may not want college games the day before a major playoff game, particularly on a real grass surface.
