Josh Selby has been training at Impact Basketball Academy for eight hours a day, five days a week.

Selby arrived in town at 208 pounds, and in the month that has passed, has trimmed himself down to 195. The daily routine at Impact includes three workouts, ranging anywhere from weights to individual skill drills to 3-on-3 games. ...

He's turned himself into the most impressive prospect among the 30 currently training at Impact under the watchful eye of Joe Abunassar, who works out draft hopefuls each spring and also trains several NBA veterans each summer, including Chauncey Billups, Paul Pierce and Kevin Garnett.

A couple of those veterans — Corey Maggette and Al Harrington — are already back to start their offseason workouts and have spent some time helping their potential NBA opposition.

"(Selby) has been the most pleasant surprise," said Abunassar, a former NCAA Division-I assistant coach. "I don't think anyone knows really how good he is."
