Actually, 4S is likely at least as strong as 4M. And a good argument can be made that it's stronger. 

Venice petitioned to be in the metro Class but was denied. They didn’t want to be in the bush leagues. 

That it would.

I agree atleast a minimum of 6 with the top 2 having a bye

As I was watching the announcement on ESPN yesterday, a thought ran through my head --  a thought that apparently ran through the head of JJ Watts, as well:  Since college football is going to 12 teams next year, why not just make this year a transition year and go from 4 teams to 6?  Based on the rankings, Michigan and Washington would get byes.   Texas, as the 3 seed, would play Georgia, as the 6 seed (for the right to play Washington) and Alabama, as the 4 seed, would play FSU, as the 5 seed (for the right to play Michigan).  Yeah, I know, I know, it would have required a renegotiation of a lot of contracts in a short amount of time (with bowls, TV networks, etc.), but it could have been done if everyone was on board.  Clearly, there were six teams that could make a strong argument that they should have been one of the final four teams.  And Ohio State could have been the "FSU" of 2023, complaining that they got screwed.  In any event, it didn't happen.  Damn lawyers.
