If the B1G adds USC, UCLA, Oregon, and Washington.... and the Big 12 adds Cincy, Houston, BYU, UCF, Utah, and Colorado..... here's how those teams finished in last years final AP Poll......
4. Cincy
12. Utah
17. Houston
19. BYU
22. Oregon
None of the other teams even got a single vote for the top 25. In fact, when was the last time UCLA or Washington was any good at all? USC hasn't been that good forever either it feels like.
Now I'm not saying I'd rather be adding those teams to the Big 12, based on brand alone, but the teams the Big 12 are adding are no slouches whatsoever. Oh.... and they all finished above Iowa too.
