Any team would be stupid not want Burkhead. Now would all of these teams trade their #1 RB for him? I doubt it. He may not fit the bill for certain teams, and I'm sure that there are a couple of better backs in the league.
The guy is good at everything, maybe not great, but good. He has good not great speed, catches the ball well, rarely fumbles, blocks well, and heck, he used to play QB. The thing that is most overlooked is that he is a very good short yardage back, he has the ability to get 2 yards when you need 1, and he is very good at going into contact, keeping his balance, glancing off of tackles, and getting you an extra 3, 4, or 4 yards. He did average over 5 ypc against the top team in the B1G, so I think that he will be just fine, barring injury.
