What happened: The Dallas Mavericks have officially named Dusty May their new head coach. May arrives as a first-time NBA head coach making the leap directly from the college ranks. He inherits a franchise with clear expectations and no margin for a slow learning curve.

Why it matters: The debate is simple: college coaching success does not guarantee a smooth transition to the NBA, where rotations, player management, and a longer schedule test even proven names. Supporters point to May's track record of building winners and developing talent. Skeptics note how rarely the college-to-NBA jump pays off right away. Both sides have a case.
