Doug Dickey's playoff expansion recommendation article with 247 is linked below:
Doug Dickey on state of Vols, fixing College Football Playoff
Dickey says that the 4 team playoff hurts teams like TN because all the elite players want to play in the playoffs. Therefore, most of the 5 star recruits end up at 5 or 6 schools that are usually contenders for the playoffs. It causes what we are seeing now with the big disparity between the elite teams and everyone else.
His recommendation is a 12 team playoff setup where the top 4 teams get a round 1 bye. Teams 9, 10, 11, and 12 would play at the home field of teams 5, 6, 7 and 8 in round 1 the week after conference championship games. The 4 winners of round 1 would then play the top 4 in traditional early bowl games in the quarter finals .. and the semis and championship games could remain similar to the current setup.
I like his idea on the playoffs and would love to see it implemented.
