And he's wearing a backpack no less!  These PhunkeeDuck things are becoming all the rage now.  It wouldn't surprise me if there's an entire pickup game full of NBA guys playing on them somewhere.

I can't quite tell if Johnson was behind the three-point line or not, but in all seriousness, Celtics fans are going to be very impressed with the range on his jumper.  As I've mentioned before, he shot 41.3 percent from deep for the Raptors last year.
