Aw, it's the JV! WELCOME BACK: Former Spurs point guard Jacque Vaughn is expected to serve as an assistant coach for the team's summer league squad next month in Las Vegas, an endeavor he might hope to parlay into a full-time gig next season. The Spurs are in search of a replacement for long-time assistant coach/head video coordinator James Borrego, who left after seven seasons to join Monty Williams' new staff in New Orleans. Vaughn, who spent the final three of his 12 seasons with the Spurs, retired after the 2008-09 campaign. He has long been held in high esteem by coach Gregg Popovich, who has called Vaughn prime coaching material. "Welcome back . . . your dreams were your ticket out. . . . Welcome back . . . to that same old place that you laughed about. . . ."
