I think that that is too low. I think OSUs offense may well score much more than that, but I agree, that unless it's technical corrections that can be done between weeks, that OSUs defense is going to get mauled by Texas. Expect that, at least during some 8-10 minute part of the game, that there will be 28-35 points scored.
I don't think they will be mauled.
I honestly think that both offenses will come out a bit tight, especially Texas.
