I think he means as a mid range jumper during game action, which TR still struggles with. He isn't a bad ft shooter, he is just a shooter who can't shoot quickly and efficiently. Give him time to set up and bend his knees (ie free throws) and he is pretty solid.
I'm not sure how I could have misinterpreted that. There was a direct comment about FT shooting. "I wish he or JJ could hit from the FT line".
