Dwane Casey is optimistic of how much Jonas Valanciunas will improve the defense of the Raptors.

“I saw him last summer with the Lithuanian national team and the Euro games in the championships — big-time energy, runs the floor, rebounds. At the worst, we’re getting a Joakim Noah from Chicago — a guy who mans the middle, challenged a little bit in terms of scoring in the paint but as far as of pick-and-rolling to the basket, he has great hands to roll and finish. He hasn’t developed that consistent outside jumpshot at the elbows yet, but something that you can’t teach — and I do know that it’s an NBA skill — is each every time he walks on the floor, he’s gonna hit people, he’s gonna play with energy, he’s gonna play hard, he’s gonna bring an energy to the court that is an NBA skill. And being seven-foot, that’s a plus when you can have your big man with that type of energy and that type of aggression.”
