I'm perfectly content with 2 P5 games a year. We desperately need the money in order of having any hope of staying competitive in the MAC. Also, if we can't go 5-3 in MAC we frankly don't deserve to go bowling.
The payouts for these P5 seem decent and as @LZIp stated for the most part they're 2nd or bottom tier P5 programs. The type of opponents that an upset, while unlikely, is possible.
