The seeding committee really needs to be on point when it handles those 7-8-9-10 teams, putting a team like UW on the 7 line can do damage to a #2 (like they almost did to UNC), but an 8/9 seed should really be a middling major conference foe for a #1 playing largely close to home. There have been several scenarios lately where the committee moves that 4th #1 seed to the backyard of a #2 (Duke had to beat #2 Baylor in Houston last year). Almost as if the committee couldn't decide who was the last 1 and the first 2, and decided to even the playing field by giving one the "easier" draw and the other the local game. Doesn't hurt that it also sells more tickets...
*(they themselves are the last team to do it, nearly 20 years ago): Florida went back to back in 2006-2007
Re: “Commentary: ACC will struggle to get five bids”
UNC easily faces the league's hardest schedule (VT, BC, Clemson, Wake once each; the balance of the league twice, KenPom commented on this http://goo.gl/9IVOl), which is as always a double-edged sword.
There will be plenty of opportunities to prove themselves to the NCAA selection committee, including road games at all 7 teams that are currently in the running for a bid and this should buoy their SOS. But, potentially finishing the season with a hard fought 10-8 record will look worse than it actually is, and given Carolina's current record in road/neutral games (2-3) that is a very real possibility.
