Yes, it's early in the college basketball season, but when it comes to Selection Sunday, games in November can weigh just as heavily on seeding as games during Championship Week.
With that in mind, I'm taking a look through the ESPN.com/ESPN The Magazine Top 25 preseason rankings to see which games on their schedules could have the biggest bracket impact. The bolded battles are the clashes I see as the biggest of the season.

1. North Carolina Tar Heels
Nov. 13 -- vs. Michigan State (Carrier Classic)
Dec. 3 -- @ Kentucky
Mar. 3 -- @ Duke
It's hard to argue with the historical significance of the Carrier Classic, but UNC's trip to Kentucky is a legitimate national championship preview. It features the nation's two winningest programs and the most talented rosters of 2011-12.
