TCU had a bad loss... Giving up 61 points to anyone is a bad loss. Ohio State lost to a tough VTech team in EARLY SEPTEMBER. Arguably a better loss, as ugly as it was.
Ohio State also beat more ranked teams, had a tougher SOS, had a better coaching staff, better players, and better performances. TCU didnt even win their conference or play in a CCG.
What's better? An complete 59-0 domination (every damn play) of a top 15 team in a conference championship game or a sloppy win over a horrendous Iowa State team. Just go watch the first half of that game and tell me that TCU doesnt look like a MWC team still. Cringe-worthy performance.
Part of Ohio State's brand is being the best damn team in the land. Can't say the same about TCU.
