Look at the Insight Bowl throughout the years. Big 12 owns the B1G's ***.
Plus this is about this year. Not other years.
The Big 12 is currently 5-8 in the Cotton bowl against SEC teams which isn't completely horrible.
5-8 since 1999, the year the SEC and Big 12 starting facing each other in the Cotton every year, but have the last 3 have not been competitive. 0-2 vs the SEC in BCS games in that same time frame I believe. Also, several OOC losses to Arkansas, but at least you don't have to claim A&M anymore. The Big 10 is 8-6 in the Capital One bowl(most similar bowl to Cotton) vs the SEC in that same time frame. The Big 10 has actually done pretty decent in the Outback and Capital One bowls given the SEC's home field advantage.
5-2 in the Insight, but 4 of those wins coming against Minnesota and Indiana. The Big 10 went 8-7 against the Big 12 in the Alamo. Not to mention, many of these games are not even match-ups from both conferences with the Big 12 almost always having the advantage, for example unranked 5-6 loss Iowa teams having to face ranked Texas, OU, and Missouri in both bowls over the years. Pretty sure the Big 10 is 3-2 vs the Big 12 in BCS bowl games since they've started, but I may be wrong on that.
Is the Big 12 better than the Big 10 this season from top to bottom? Yep. I'm not disputing that. I just get a kick out of guys like HFCS thinking the Big 12 is at the SECs level because they are having one good season, coming off a pretty bad one. Big 12 fans like to make fun of the Big 10's bowl record last season, but they did equally as bad against a bunch of unranked opponents.
The Big 12 and Big 10 have actually been pretty similar over the past 10 years. Both have NC winners(although the Big 12 has had one more), both have had teams get completely embarrassed in NC games(Ohio State and OU) and both have struggled against SEC teams. Really, its been the SEC and everyone else for awhile now. I'll admit the Big 12 got robbed this season too with not getting 2 BCS teams and I was hoping OSU did play in the NC game, because I won't watch an SEC rematch. But Alabama and LSU are the two best teams IMO and both would beat OSU.
