I expect Cobb will get over 50 easily. But at the same time, OSU's strength defensively is against the rush and the Gophers rely on the run game heavily, to the extent that teams can load up on defending the run at times when playing the Gophers (something you can't really do when playing MSU). OSU's strength is not their defense but you don't want to get too predictable against them.
OSU's offense has been very strong lately, there has only been one game over the last 8 weeks that they really struggled offensively, the PSU game. Personally I felt watching it that PSU played way above their average in that game but they don't have the #1 rush defense in the country by accident, they can put the clamps on a lot of teams when they put their mind to it. If the Gophers can play D about as well as PSU did, then the 50-point prediction will look foolish. But if you put the shoe on the other foot and look at how the Gophers gave up nearly 300 yards of rushing against Purdue, an objective reporter might believe that OSU will be able to run the ball on the Gophers fairly well because Purdue was able to & reason that if you can't stop the run it can be a long night defensively.
As has been proven in college football, previous games have NO prediction of future outcomes. Play the damned game and find out.
