I really hope you're right about the outcome of the game, but I don't think we can draw that much confidence from those numbers.
As for the Illinois game, you have to admit that Mizzou's D adjusted at the half and shut down Illinois's run game for the most part in the second half.
And to be fair, those San Diego St. numbers aren't quite as telling as they look at first sight. Ronnie Hillman got 228 yards on 23 carries for an average of 9.9 YPC. Two of Hillman's runs went for 93 and 75 yards. That means that 168 of his 228 yards came on two carries. Of course those two carries still count and Mizzou gave up those big plays, but it's not as if Hillman was just gashing Mizzou's D all day. In other words, he only averaged 2.8 YPC on those other 21 carries. Again, those yards still count, but they happened on two significant breakdowns instead of repeated breakdowns throughout the game.
