Mismatches slice both ways. You might have a big underneath such as Zeller and Henson but when you are going against the dribble drive you have to pull them out from under the rim where they are the most effective. Otherwise you are going to have four or possibly even five guys who can spread the floor and stroke it from deep.
As for other teams, the one outside of UNC that worries me next season is UConn again. They are losing Kemba but the rest of that team is still young and very talented. If Shabazz Napier and Jeremy Lamb pick up where Kemba left off and they can get some production out of Boatwright they are going to be scary again.
