Did Pat Riley create Showtime East in New York and Miami? No, he built the offense around the players at his disposal at the time, which is exactly what Nate M, who coached during a different NBA landscape setting - the league, as whole, was still transitioning away from the dull, grinding, 84-81 brickfests circa '97, era/rules - and just how many "gazelles" were at Nate's disposal in Seattle or Portland?
If Nate's smart enough not to sit his top three scorers, as Vogel did, at the start of the fourth quarter of a playoff game, and/or smart enough not to remove his best rim protector for the final two seconds of an ECF road game in which the Pacers were ahead, while attempting to defend LeBron James and company, he's more than qualified as Pacers head coach.
As for Jefferson, pace, shmace, the idea is to score more points, and Jefferson improves bench production exponentially. Still, speaking of bench scoring, the Pacers need another 2G or combo guard, so that Ellis can assume the role of sixth man.
