Cody Williams looked really good at the start of his college season. Then he had a series of injuries. He had a high ankle sprain. He got hit in the face and had to play with a mask. He also had a broken hand that he was recovering from at some point. Similar to Keyonte a year ago, I think Cody is better than he showed later in the season.
However, that's also the question with Cody--can he compete well enough physically? I was hoping that he'd add some strength and really attack his pre-draft process, but he didn't quite do that. He also weighed in at just under 180 lbs at the Combine, and quite frankly, he doesn't look like he's physically ready for the NBA. He's going to need 15 lbs as a starting point, and preferably 20+ lbs if he's going to hold his own against physical defenders. I wonder if his frame can carry that. He's also looked a bit physically awkward, like he's still getting used to his body. However, this might actually be a good thing if it means he has an opportunity to tighten things up as he matures.
The bet on Cody is that physical development will take place over the next 2 - 3 years, which when combined with his length, feel and scoring instincts, makes him an impact player. At the same time, he should be a fairly versatile defender. However, I wouldn't expect him to do much at all in his first year or two.
