Top 4 will get roughly 3 weeks off to rest and heal. However, any playoff qualifiers that don't play in the CCG, also get 3 weeks rest before their 1st round game.
Top 4 obviously get advancement without risk of losing and without wear and tear. However, 1st rounders may have momentum, coming off a big win and have already worked off any rust.
Top 4 have to gameplan for two teams, then refine the week of, based on wrinkles and pivot to one of the team plans. 1st rounders can set up two firm gameplans out of the gate: one for 1st round and 1 for 2nd. I could see the CFP re-seeding after round 1, in the future.
I'm sure the benefits of Top 4 outweigh the consequences, but it will be interesting to see how it plays out. It's going to be amazing to watch and even better if we are somehow part of it.
