I heard that Elliot's knee caps were a condition he had since he was young, and that they'd dislocate easily. It was a simple and relatively very safe operation to repair them, that posed no risk to his future health.
His shoulder was bad luck.
The little I saw him play, he just looked like a good player. He had confidence. He had a little swagger. He had athleticism and intensity. I don't know how good he'll be, but I have a hunch he will be pretty darn good in a couple years.
