I think you get most of the real contenders with the 4 team playoff. I loved NYD games more this year than I have in a long time, if ever. I don't think I want the 8 team playoffs, although I did before Jan 1 of this year. I thought it could not have been any more perfect. I like that the Big 12 had intentionally stayed below the limit so they didn't have to chance of the top team losing a CCG and getting knocked out, and essentially knocked themselves out of the running. If they had a CCG, then the winner would almost have certainly been in the final 4. And almost certainly been knocked out by Bama, IMO. Which would have supported no playoffs at all, since No 1 and 2 would be in the final game. I like that 2 and 4 are the teams playing.
I won't hate a 8 game playoff, but think they should be on campuses, and not take away more bowl games from the teams that are not top 8. As it is now, we have 4 teams playing in 3 major bowl games, instead of 4. Go to 8 teams and keep the bowl games as where they play, and you get 8 teams playing in 7 bowl games, instead of 14. Keeps 6 more teams out of the bowls, unless they start a couple new ones. And I like 6 win teams getting to play, extra practices, a good final game for seniors that have given they heart to a certain time for 4 or 5 years. Higher 4 seeds basically get a home game. Yes, makes it harder for the 5-8 seeds, but if you want a shot.. you have one. If they make it through, they proved they belonged for sure.
