Seth Davis did a piece profiling pro prospects by talking to scouts. Here's the blurb on JWill:

He gets a double-double every night. He's a rebounder, he's tough, he can score it. If he could make a free throw he'd be putting up bigger numbers and getting more notice. The question with him is the athleticism -- he's a below-the-rim finisher. You wonder if there's a chance of development where he could step out and make a jumper. His free-throw shooting makes you wonder, but there's a place in our league for that kind of guy"
