I like expanding the playoffs because I like more football. I think that a G5 team should get in but with a caveat - they have to be in the top 12 or something similar. I would have liked to see UCF have a shot a couple of years ago, and there have been some great teams that would have come out of that group - like the TCU, Boise St., and Utah teams from the late 2000s.
Also probably controversial, but I think that the amount of teams in an expanded playoff should be limited to two from the same conference. I like seeing different conferences play and different styles go against each other. The Wake/A&M game from a couple of years ago was one of the most exciting bowl games in recent history.
Yeah, the SEC's not voting for that.
