It probably has a lot to do with the explosion of 3pt shooting. That component was already hard to project -- look at how many great NBA shooters were not top picks, and how many great college shooters struggled in the league -- likely due to the different distances, but now the uncertainty is magnified. FT shooting is a constant.
From the physical tools and style of play, I'm surprised MKG hasn't been mentioned more. I also think that might be the answer to why Little slid so far. MKG was a major overreach for an offensive project. We even talked about it at the time ... late 1st or early 2nd, he's good value.
I don't know that I ever saw Little play this year, and if I did, he didn't make an impression. I had the NBA.com draft ticker open yesterday and looked to see who we had picked when the time came ... and was disappointed to see we had taken a 6'4" SF. Fortunately, everyone else lists him at 6'6". Whew!
