Unless a team thinks he will be a contributor, the more likely choice is to fill the last roster spot with a first year guy because the rookie minimum is a little more than half of the second year minimum. Cap room will prevail. However, he will make a roster if a team thinks he can be the fifth guard in its rotation instead of the sixth (who doesn't play in more than than he does play).
If he doesn't make a team next fall, he will choose between making s six figure salary in Europe and the NBDL, 10-day contracts, and hoping to fill a roster spot that opens due to injury. At this point in his life, I wouldn't guess that he considers coaching to be an option for next season.
Aside from Hansbrough's playing aspirations, why would anyone think hiring a guy with zero coaching experience is the way to upgrade the coaching staff. This staff needs another proven recruiter. This staff needs an assistant who has proven he can teach defense. It doesn't need a guy whose qualification is that he yelled at his teammates a lot.
