Semih was a success in the Giddens draft. Lester Hudson looks like he can play, and could be in the league next year. (At last look, he was leading the Chinese Basketball Association in scoring). Harangody could last for a bit as an end of roster player.
We'll see on JJ and Moore.
So, his misses are really Giddens, and potentially Bradley. Giddens didn't last, but he was the 30th pick in the draft, in a draft where Danny repeatedly said he didn't like the talent. Sure, a lot of us wanted Chalmers, CDR, or Jordan, but Danny wanted a more mature guy who could compete right away. It didn't work out. With Bradley, Danny took upside. It's clear Bradley has the athleticism and the defense to stick in the league; time will tell if the offense is there.
It's hard to condemn somebody for their drafting when they've picked 19th, 30th, and in the 50s. Danny doesn't have any huge success stories, but historically, very few GMs have.
