The New York Post (Marc Berman) reports:  Warren LeGarie is one of the most important movers and shakers of the NBA you’ve never heard of. Best known for founding the wildly successful NBA Las Vegas Summer League five years ago that has knocked out all competitors, LeGarie is also coach Mike D’Antoni’s agent and a key reason he wound up in New York and not Chicago… LeGarie is the agent for five other NBA head coaches - Rick Carlisle, George Karl, Mike Dunleavy, Mike Iavarone and Mike Brown, plus Nets GM Kiki Vandeweghe.
