It was hard to gauge how good UConn was in week 1 since NCSU was clearly keeping things simple for ND the following week. Since then, they got blasted by Ga St and worked by FIU until they made a comeback. I assume they don't have a lot of returning players from last years team.
I don't expect Duke to do with State did, there's a difference between hiding stuff week 1 against an inferior opponent and a big match up the following week vs going into week 4 where you need to make sure you are firing on all cylinders. Because of the basketball rivalry, UConn fans will actually care more about this game than if they were playing another P5 school and 0-3. That said, I don't think they have the ability to beat Duke or even make it close (provided Duke is playing their best). I'd take NU over UConn right now.
