BYU is 7-2. They have losses to Boise state and Baylor, but have some nice wins too including Virginia (6-3), Utah State (6-2), Utah (5-3), Arizona State (5-3), and Washington State (5-4)
Should have had BYU ranked last week around rank 20. Good win over a good Virginia team shoots them up, coupled with several 1 loss teams picking up their second loss.
BYU sits at #18 this week, with a bunch of decent wins; I would consider all of Arizona State, Utah and Virginia at home and Utah State and Wazzu on the road as decent wins. However, the home loss to Boise is not good, and they also lost at Baylor.
