re: Who had a worse weekend, the ACC or the PAC-12?

Out of the two in the OP it's the ACC but IMO the American had by far the worst weekend out of the FBS conferences.

They started the weekend with news that Cincinnati, UCF, and Houston, are probably leaving for the Big 12 as early as next year and then they went 4-7 w/several bad losses. Their only win of note was by a team that is leaving the conference. The only other bright spot was Tulane playing so well against OU.

Wins
UCF over Boise - 36-31
Cincy over Miami Ohio 49-14
SMU over Abil Christian - 56-9
Memphis over Nicholls - 42-17

Losses
UC Davis over Tulsa - 19-17
App St over ECU - 33-17
Marshall over Navy - 49-7
NC State over USF - 45-0
Rutgers over Temple - 61-14
Texas Tech over Houston - 38-21
OU over Tulane - 40-35
