The Detroit Pistons are considering re-signing Jose Calderon and Will Bynum.

Both Calderon and Bynum are unrestricted free agents.

Calderon recently turned down a contract from Sacramento, while Bynum has garnered interest from the New York Knicks and Chicago Bulls.

Chauncey Billups is also being considered by the Pistons, who have just three guards under contract – Brandon Knight, Rodney Stuckey and Kim English -- for 2013-14.
