Solid stuff, Mark and spot on. I agree with your assessment that Notre Dame seems to be a bit out of place in that top tier. They are only 1 game up on UNC and with 0 games against the best teams in the conference so far, I feel like ND shouldn't really be placed on a different level than the Tar Heels, especially since the computers seem to think UNC is the better team.
It is still early enough in the schedule so that teams could be mis-tiered relative to their strength. I mean, Va Tech is in your bottom 7 but is the 3rd best team in the conference according to the advanced metrics. Ok, those 5 losses almost certainly rule them out for the double bye, but they would seem to be good enough to still have a decent shot at the single bye. They've got UNC, Miami, and FSU over the next 10 days and the computers say they have a very good shot in all of those games (they will be a decent favorite over Miami). Winning even 2-out-of-3 in that stretch could put VT right back in the middle-tier race.
