Last few weeks....
Okla vs. Okla St., Okla wins 1Q 7-3 (spread was -3 or -3.5)
Okla vs. Texas Tech, Okla wins 1Q 7-0
Okla vs. Texas A&M, Okla wins 1Q 21-0
Okla vs. Nebraska, Okla wins 1Q 35-0
Okla vs. Kansas St., Okla wins 1Q 28-14
The last loss was against Kansas when it was 7-7.
Hope this helps.
Especially lately they have been on fire in the first quarter. I'm going to see how my Florida bet works out and then I might add this one later.
Good luck.
