--- Veteran point guard Darren Collison will decline a player option for 2014-15 with the Los Angeles Clippers and become an unrestricted free agent in July.

Toronto Raptors star Kyle Lowry, Eric Bledsoe, a restricted free agent for Phoenix Suns acquired from the Clippers in 2013, and Isaiah Thomas of the Sacramento Kings headline the free agent point guard crop that is heavy with off-the-bench options similar to Collison (Mario Chalmers, Nate Robinson, Greivis Vasquez and Shaun Livingston).
