A couple of notes on the defense that has possibly been talked about indirectly here:
In the final 35:18 of regulation OSU scored just one TD in 8 possessions.
Before the game on Friday OSU was averaging 3.42 pts/possession & TDs on 43% of possessions. Against ISU in regulation OSU averaged 1.31 pts/possession & Tds on 16% of possessions.
If you include OT the Okie State offense scored 1.6 pts/possession & scored a TD on 20% of possessions.
