Hate to see it happen to such a talented young kid with such potential, but when the kid goes to Duke, all you can really say is GOOD RIDDANCE.
Duke is still a top 5 team without him and might even still be #1. All this means is that Singler moves down to the 3 and the Plumlees start in the front court. Andre Dawkins will have to take on more responsibility, and he is MUCH improved from last season.
Instead of just being a shooter, he can take guys off the dribble, either for a pull-up jumper or for a hard finish at the rim.
Duke is certainly worse than they were when they had Irving, but just how much worse are they?
