What doesn’t matter? Wrestling? I didn’t say it did. Wrestling matters to me. And since all Big 10 schools have wrestling I am hopeful that a new member without it would add it.
As for Texas, they are a huge team surrounded by big markets, it would be bad news for the Big XII to lose them.
It doesn't matter which teams go into the Big-10 or leave the Big-12 since the SEC will still dominate both.
