I think I was one. He was a poor shooter in college, then I go to a jazz scrimmage age he shot poorly and I noticed a hitch in his shot, then he shot poorly in summer league, then he shot poorly at the beginning of the year. (I think he went quite a few games without making a shot iirc as missed his first handful of shots on the year. Like his first 10 shots or something)
Hell, even when I heard about his workout for the jazz pre draft I heard his three point shooting in that workout and it was nothing special. (Seems like it was between 50-60% from three or something with no one guarding him)
Dude has exceeded my expectations by miles with his shooting.
From day one after we drafted him and I saw him up close I saw lots of skills but I said it over and over again like a broken record at the start of the year. If he doesn't become a good shooter then he is a bust regardless of his size, ball handling, passing, etc.
Well, he didn't just become a good shooter. He became a great one it looks like.
