Stephen Curry's smooth stroke reminds me of how smooth and dominating Shawn Respert was in his senior year at Michigan State. Respert was an under-sized shooting guard as well. He arguably could create his own shot though. Now look at how successful his pro career was.
Respert was dealing with cancer diagnosis during his time in the league too, something he didn't go public with until long after his retirement. I loved Respert in college, and couldn't figure out why it didn't translate for him, because he was given an opportunity.
A personal story about just how great a shooter Horny was that I've told before on here.
I went to see Hornacek against the Nets at the old CAA many years ago, early in his Jazz career. We got there really early, and were sort of tooling around courtside, even though our seats were up higher. We were down on the floor level under the Jazz hoop, when Horny came out with a trainer to work out a little. He was the first guy out, and after a couple of quick dribbling warm sequence, he went to the free throw line to start his shooting warm up. He shot three free throws, all of which went nearly dead through, just grazing the back side of the front of the rim. He yelled to his trainer that the rim was a quarter inch high, and went to the other end. The officials came out and measured, and I wouldn't have believed it if I wasn't there, but it was just over a quarter inch too high. He figured that out after three shots from the stripe. The technicians came out and lowered the rim, they use a calibration unit from the floor up. Even they were talking about it.
I know everyone listed is a great shooter, but I'm not sure how many guys could do that.
I'd also say that Horny was a better passer, and more creative ball handler than pretty much anyone else listed. He was able to let Stockton play off the ball some when he was hot because of it. And he was a really good player prior to coming to Utah too, so while the system probably accentuated his skillset, he definitely wasn't a product of it.
There are certainly guys for which this question makes tons of sense. Jason Kapono, Kyle Corver. A lot of it is opportunity. In the case of Reddick, I was concerned with just how big a star he was in college. What would his mentality be like when he wasn't getting everything run too him anymore, which even his most optimistic supporters had to know was going to be the case. I think eventually he'll find that niche. That's the case with a lot of college stars that you know aren't going to translate into that same role at the NBA level. There's a mental approach that needs to be adjusted, and it doesn't always happen.
