With an experienced offensive line in front of him, Harden has set high goals for himself, saying he wants to have 1,300 yards going into the Mid-American Conference Championship Game, and that he wants to finish the year at better than 1,600 yards.
Note that the Ohio record is 1434 yards by McRae in 2007, followed by Steveland Hookfin at 1315 in 1998. I'm not saying he can't do it - if he stays healthy, and if they line is as good as I think, it's not impossible the he could rack up some 200 yard games.
