Grizzlies beat reporter Ronald Tillery has been taking notes during some informal Grizz workouts/pick-up games, and for the first time in Memphis history he's watching a fiery, healthy, competitive spirit bubble up amongst the players during practice. We're talking about Rudy Gay verbally sparing with others, Kyle Lowry and Javaris Crittenton battling it out every play, and O.J. Mayo and Darko Milicic having to be separated teammates. Sounds awesome! HBO really ought to start filming a NBA Hard Knocks series. I'd watch.
