10 B1G teams qualified for a bowl, and Vegas has all 10 as dogs:

1. Illinois is + 3 against LaTech
2. Rutgers (+4)  UNC
3. PSU (+3.5) BC
4. Nebraska (+6) USC
5. Maryland (+14) Stanford
6. Wisconsin (+7) Auburn
7. MSU (+1.5) Baylor
8. Minnesota (+7.5) Missouri 
9. OSU (+9) Alabama
10. Iowa (+3.5) Tennessee 

Interestingly, the Buckeyes are a bigger dog than Nebraska, a team that has exactly zero chance of beating USC. In fact the only team given less a chance of winning is Maryland against Stanford. I'd say the B1G probably goes 3-7 in these games with 4-6 being the best case scenario and a less likely scenario than, say, 1-9 or, heaven help us all, 0-10.
