It would just eliminate the threat of a top 5 team being knocked out of the NC race in the last week or two of the season. They would be :dull: weeks.
Playoffs = the rich get richer.
Playoffs= more than one meaningful game
winning the rose bowl doesn't mean anything if it's not for the NC
unless you're gambling on it or your team is in it, most people don't care
Seriously though, what purpose is college sports without a champion? What other college sports don't have a true champion? And with so much concern about maintaining the interest and relevence of bowls or the regular season, why would any of that matter without a champion? At that point what is anyone playing for? That is just weak sauce, every high school sport crowns a true champion. Hell, they even have a true champion in Little League Baseball. This is the biggest of big time college sports.
With the money and attention paid to college sports, football in particular, if you truly have some principle based view that it doesn't need a championship, then you have about 10,000 issues with college sports that come ahead of how we handle the football post season. Might as well just scrap the bowls and the playoff idea all together and hand out ribbons for participation at the end of the year.
And while you may not have a thing about the Rose Bowl, the majority of those in the Big 10 do. It took some extra manuevering to get them on board with the BCS in the first place because of their place in that game, and their fanbases clearly value making that game over all others, maybe even the actual title game.
As many have said/alluded to, the poll needs to include a "hybrid" option. Some playoffs but some bowl games in addition.
As I've said before, playoffs would solve nothing. If there were an upset, there would be just as big an uproar about who "deserved" the national title as there is now.
I think it's fine if people want the excitement of a single elimination tournament -- but I'd like them to argue for that system for various reasons (exciting, "less" controversy etc.) However, if you will realistically think about it -- the BCS has by far the greater chance of matching the 2 best teams in a "national championship" game.
One more thing -- don't compare college football with college basketball. There are WAY more basketball teams that are realistically national championship contenders. A 64 team tournament works well.
A final note -- a multiple game "neutral" series is the "best" way to establish which of 2 teams is "better". Not enough time in college to do that for football or basketball (where the NBA obviously does, but not the NFL for injury/stamina reasons (I guess)).
There isn't enough parity in D1 football to do a fair, proper playoff system. When you have teams in non-BCS conferences playing virtually no ranked teams to go undefeated and grab a #7 or #8 seed you're going to have some people legitimately ****** off.
