27, 56, 47, 40, 46 are OUs last 5 games points allowed.
None of these teams were Alabama. Alabama knows OU could potentially hang some points on them - they not going to take the foot off the gas unless they up 35 and running the clock out in which case Bama covers and the total goes up in flames.
I’ve been wrong before and have looked foolish doing so but I just don’t see Bama scoring less than 42 in any scenario and that’s with Hurts playing the whole game.
