MIAMI -- It's starting to look like one of the bigger offseason challenges for the San Antonio Spurs:

Keeping hold of renowned shooting coach Chip Engelland.

A tweet Tuesday night from ESPN's own Fran Fraschilla was a handy reminder of the impact Engelland has had on refining the shot of Spurs swingman Kawhi Leonard. Those who watched Leonard's scuffles from the perimeter at San Diego State never envisioned NBA Finals nights -- even if it was only one night -- where Leonard could outgun LeBron James.

Leonard, though, is merely one of Engelland's high-profile pupils. Spurs teammates Tony Parker and Danny Green, as well as former Duke stars Grant Hill and Shane Battier, are some of the more prominent students to make career-changing strides under Engelland's tutelage.

Only now one of Engelland's biggest fans on the planet is the new head coach of the Golden State Warriors. Steve Kerr succeeded Engelland as the top perimeter gun at Pacific Palisades High School in Southern California and, according to NBA coaching sources, wants to bring him to the Bay Area to sit on the Warriors' bench.

The Spurs have managed to fend off all past interest in Engelland and presumably will fight hard to hang onto him now, such is the reverence for his work with the likes of Leonard, Parker and Green. But with Kerr in pursuit and new Utah Jazz coach Quin Snyder also said to be in the hunt, it's only getting tougher.
