Is it possible for someone who knows something about this to give a quick list of who we route for to make this happen?
Okay, from the B1G you want:
Wisconsin over Minnesota
Northwestern over Illinois
Iowa over Nebraska
Purdue over Indiana (least likely of the B1G games).
Those four are absolutes. If all 4 don't happen the B1G will have enough teams to fill the Pinstripe (they'll leave the Detroit Bowl and maybe one other bowl open tho).
And then you want 9 or more of the following to happen as possible to fill the 80 bowl spots (so no 5-7 teams can qualify):
ECU over Cincinnati
Tulsa over Tulane
ODU over FAU
SJSU over Boise
Buffalo over Umass
Washington over Washington State
Missouri over Arkansas
Virginia Tech over Virginia
Kentucky over Louisville
Kansas St over WVU and Kansas
Texas over Texas Tech and Baylor
S. Alabama over either Ga Southern or App State
La Laf over both App State and Troy
Georgia State over both of Troy and Ga Southern
If all this happens, you then have to hope the B1G opts to send teams to both Farm Bowl v P12 in SF and the Gator Bowl v SEC over the Pinstripe Bowl v ACC. Those 3 games are the same tier for BIG and they'd be able to fill 2 of the 3.
So, in short, UConn is a lock for Pinstripe
