One of the plays that really stood out to me was when Ennis casually decided not use the screen and completely left his defender behind on his way to the hoop. I'm still amazed at how fast he can be when he needs to be.
Jose Calderon when he was pretty good some years back. Keeps it simple, will take it to the rim from time to time, Toronto actually had an efficient offence for the Calderon- Bosh era, despite having to play that big stiff Bargnani. It was the defensive efficiency (due to Bargnani, and Calderon) that was historically terrible.
Hopefully Ennis would develop a shot like Calderon did, and not be as bad on D.
He reminds me of Mark Jackson too, I think they have similar skills and play the game in the same manner. He doesn't out-athlete you, overpower you, out-quick you, nor does he try to outscore you (unless he has to) - he just plays smart, calm and in control and tries to do what's required of him to win the game.
