I like him way more than Jennings--I know Jennings has matured and obviously has the potential that come with undersized scoring guards, but I do have reservations since he's barely played at Europe and I'm not sure about his receptiveness to defense and passing, two of the things that we need more in our point guards. He's not a bad pick--I like him more than Harden--in that he provides point guard quickness on top of the legit scoring, but I think Curry will provide us with smarter play, consistent three point shooting, and potential passing ability (he averaged 6 assists per game in college). But again, we'll see...
Also, to address the OP, I absolutely agree...Petrie loves shooters, and honestly he may try to make up for the Quincy Douby mistake by drafting a guy similar to his prototype. I think Curry has several things going in his favor that Douby doesn't--he's intensely competitive and really carried his team through the big games, but most importantly showed the passing ability and unselfishness that Douby completely lacked at the college level. Those two alone should make him a solid NBA player in some capacity.
