I like the Vegas line of 3.5 but I think it could go either way. Atomic has 34 to 30.
My heart wants the defense to show the change with the new DC and hold to 21 points. Keep in mind I only expect 10 possessions and 12 max.
But, I also know that your QB and WR are going to target our weakness. 28 would mean ~6-8 stops. I am thankful your QB is not mobile. 28 to 21 points sounds about right.
I think GT will score 2.1 (average) to 2.8 (if the team has not seen the option a lot and has issues with the run) points per possession 21 to 31 points.
Either team can win. If it rains, I don't know, maybe USF. If it does not rain, I'll take GT to cover the 3.5.
