The Sweet 16 starts Thursday, and NBA scouts and GMs are positioning themselves around the country for another round of evaluation. But we're casting our gaze a little further into the horizon.

We debuted our first full mock draft Tuesday and within a few minutes were getting a lot of feedback from NBA general managers. A couple of themes have arisen throughout the day:

1. This draft looks incredibly deep if everyone's in. But not everyone is going to be in. Florida's Patric Young has already said they are returning to school. Several other lottery picks, including Indiana's Cody Zeller, UNC's James Michael McAdoo and Baylor's Quincy Miller, are all strongly leaning toward staying in school, too. Taking those five out of the first round changes things.
