Teams with those spreads win about 60% of the time.
Texas A&M is a 3.5 point favorite and "should win" about 58% of the time.
Alabama is a 5.5 point favorite and should win about 60& of the time.
By "should win", of course, I mean teams in the past with those spreads win about that often. The possibility that one of them loses is then about 65%.
Kirby says he wants to be in the CG, which is what he should be saying. If UGA misses the CG it'll be interesting to see if they get dropped out of the #4 slot, presuming they beat Tech.
UGA is a 13 point favorite over Tech, which to me looks like an overly large spread.
