When the Miami Heat added LeBron James and Chris Bosh in the summer of 2010 to form a star-studded trio with Dwyane Wade, Mario Chalmers sought advice from a surprising, but perfectly logical source: Rajon Rondo. If anyone could relate to the challenges Chalmers would face as the point guard on a team with three stars, it was Rondo. The Celtics point guard was thrust into the lineup alongside three future Hall of Famers — Paul Pierce, Kevin Garnett and Ray Allen — in the 2007-08 season and helped guide the team to an NBA title. The guards developed a mutual respect in college after Chalmers' Kansas squad beat Rondo and Kentucky in 2006. They reconnected at Alonzo Mourning's annual Summer Groove charity event before last season and exchanged phone numbers.
