UF and TAMU right off the bat. Also Baylor.
And UConn (!), BC, Syr, Cal, Harvard, and Pur.
Regarding Purdue and the letdown factor, my numbers show that conference road dogs are 3-2-1 ATS after winning at home against a team that beat them by 50+ in a shutout the previous meeting. (OSU beat Purdue 56-0 in 2013, the last time they played.) The most recent occurrence of this situation was last year, when Cuse lost but covered at Miami a week (actually 8 days) after avenging a 54-0 loss to Clem. The situation has occurred in the Big 10 with Illinois covering at Indiana in 1986 after avenging a 59-0 loss to Iowa and with Indiana covering at Michigan in 1998 after avenging a 62-0 loss to Iowa. The presumed "celebrating" away dog lost twice in this situation in PAC matchups and pushed two years ago in a CUSA game to round out the 3-2-1 record.
Perhaps Georgia Southern, La Tech, W Mich, even Kansas.
