Agreed, he really needs to show a jumper to have a shot in the league. If you're a big guy in the NBA right now, you need to be able to protect the rim or be able to space the floor. McKay hasn't shown the ability to knock down jumpers yet and I don't think he has the size to get minutes on his defense alone. But he still has another year, so maybe he shows a much more well rounded offensive game this year.

I'll stop now.
edit: PLUS McKay blocks shots.
