It appears that the number of Saturday MAC home games was one fewer, but only because one of those was a Sunday (Akron). I'd suggest another couple factors to consider in the reasons for the drop in attendance:
1) No Marshall game - that's always a big non-conference draw, and we had it in 2012-2013.
2) A big outlier in the 2012-2013 season that doesn't happen during most seasons was the Wednesday night Akron game that drew 11,100.
