Jonathan Givony, proprietor of the excellent and always useful DraftExpress, spent some time at the Chicago draft combine interviewing prospects. The interviews lend some insight into each player's character and self-perception and also illuminate exactly how the curious courtship between prospects and teams goes down. You can see all of the interviews here, but here are a couple that might be of particular interest. Gotta watch 'em all.

I take more from these than I do from shuttle runs and height without shoes, but maybe that's just me.
