With the Golden State Warriors back in South Florida on Sunday, and with Dion Waiters having converted a pair of critical late 3-pointers in Friday's victory over the Charlotte Hornets, Miami Heat Erik Spoelstra again found himself talking about the need for more. But it wasn't about more dramatics, such as Waiters' game winner last season against the Warriors at AmericanAirlines Arena, or even Friday's pivotal conversions. "Now," Spoelstra said ahead of Sunday's game against the defending NBA champions, "the other side of that is helping him improve all the other 45 minutes of the game offensively, which he is coming a long way." In the wake of rewarding Waiters with a four-year, $52 million free-agent contract in July, the Heat are seeking a four-quarter contributor. "I really like the progress he's making," Spoelstra said of Waiters' season progression. "I know his shooting numbers aren't showing it right now, not necessarily his turnovers. I think those will come down. I think his shooting percentage will come up, because he's starting to understand different reads, different coverages, the responsibility of having to make plays for our basketball team.
