I'm not sure you're actually in the minority. It seems to me that most people are skeptical, hence him being seen as a 2nd round pick.
He's a tough one because he came into college with a reputation as a good shooter in the mid-range and his jumper didn't really start to go down until the very end of the season. You're right that if he legitimately can't shoot, he's almost certainly not going to pan out in the NBA. I'm also always a bit skeptical of guys that have to work as hard as he does to get good shots off; I tend to view things like selling pump-fakes, being able to just keep defenders off-balance with his unique hesitations and stuff as the sorts of little things that can take you from being a good player to a great one, but I'm not sure how comfortable I am with someone that legitimately needs to depend on it to create his looks.
Having said that, finding guys that have the touch around the rim that he does is very difficult. Finding guys that are as good at drawing fouls as he is is very difficult. And I think he showed plenty of flashes in terms of his passing and defense to potentially be excited about. I think if he can keep defenses honest with his jumper, the driving game will be effective for him in the NBA but that's a big if. For me, he's the type of guy I'd like to take a flier on at the end of the first round; if my Bucks ended up with a late 1st round pick this year for some reason, I'd be happy to take him. But I'd be lying if I said I was confident that his game will translate to the NBA.
