IMHO (Ha!!), TCU could get better if they played other teams. But that's a big "IF". The other teams have to agree to play him - which they WONT!!!
There were several articles written about Florida State in the 80's while they were an independent; they were always willing to play the big teams. They won some & they lost some. But they GOT BETTER & BETTER & as you know, the rest is history.
But now days, being not apart of the bcs-BS, the cartel members WONT PLAY THE FROGS!!!
Sure you can come to the party, but you have to stay outside. If you're invited in (to one of "our" bowls), you have to sit at your own table.
