To me the real bad draft by Danny was Giddens.
Fab Melo was a long, big guy who can block shots. Plus he had 2 picks so he took a risk with the second after getting a steal at the first. Didn't work out but you could see why he was drafted. I think it was Melo or Ezeli, and Melo had more potential while Ezeli had better floor. Didn't work out but good try.
James Young was projected to be a big guard who can shoot and was young. Upside is the key. Nurkic went to the previous slot and Harris had more physical limitation than Young. Again another shoot for the fences that didn't work out.
Kelly Olynyk was considered a safe pick, while Giannis was a shoot for the stars kind. This time Ainge choose the safer option, but was on the wrong side of it. Olynyk still outplayed his draft slot though.
Giddens meanwhile was a huge question mark. He was from a smaller program, had question marks on his attitude, who wasn't polished and relied on his athleticism. These kind of guys you pick for the upside, but there was the problem that Giddens was an older rookie.
