Injury concern is definitely there for Wemby especially with a stress fracture in his history. Chet doesn't have an injury history and I'm not concerned with him being injury prone but he absolutely needs to put on 20+ lbs if he is going to be the great rim protector at the NBA level where they're better trained to go into the body of rim protectors.
I do get that Chet and Wemby are easy to compare to each other but I see them as very very different prospects other than being thin, tall, and skilled. Just like everyone on here though I'm just a basketball junkie and not an NBA scout so it's all just fun
