Harley doesn't have a clue about coaching basketball but he does make fantastic motorcycles.I don't know who said everyone would transfer, but don't sit there on your high horse and act like you predicted not a single person would transfer.
Any rational person would've expected player movement after a coaching change. It's pretty standard. Most weren't rooting for player movement, it's a very pleasant surprise that Harley is able to keep everyone together... at the moment.
