1. Only three conference champs.
Notre Dame with there schedule deserves to be in. So I see no problem with this.
2. A team gets in who would have lost to a team with a losing record.
We all know this isn't going to happen so moot point.
3. A two loss team gets in
I think this might happen 50-60% of time in future so sure it is big deal now but not in future
4. A team gets in who has already lost to another team that is in
Lost by 2 points in a monsoon. That game was awesome to watch and a rematch would be pretty sweet.
