After being bored enough to read some more of that shit, I do think they truly believe the Big XII to be superior top to bottom to the SEC. They believe the SEC's dominance is purely media hype.
Granted, it's obvious that they are fucking around with about 90% of it, but I really get the sense that they're pretty confident and they really do think the SEC is extremely overrated. It appears that they expect to win in a shootout, and there is basically no chance that we blow them out by two touchdowns or more.
For example, I don't think this guy is being satirical at all:
Books might bait all the SEC-SEC-SEC lemmings at 7.5, but I doubt it's much over that if at all. Most outside the SEC-SEC-SEC realize what a fluke the barners were last year & how evenly matched these teams really are. The best team in your overhyped league got absolutely skull-mumped by OU in the Sugar, NU (a mediocre big 10 team) handled Georgia pretty easily and y'all needed MIRACLES at home to beat both. Talk to me about giving up 21 to piggy AT HOME . They're worse than Iowa State.
However, the proper response to that stuff is pity, not the "Nuh uh, our dicks' bigger" responses I see over there.
