Clippers to Sign Jamal Crawford and Chauncey Billups

According to Broderick Turner of the Los Angeles Times, the Clippers will be signing free agent guards Jamal Crawford and Chauncey Billups. According to Turner, Crawford will be signing a three-year, $15.7 million deal while Billups will sign a $4.3 incentive-laden deal for a season.
However Marc Spears of Yahoo! Sports is reporting:

The 35-year old Billups played 20 games with the Clippers this past season before suffering a season-ending left Achilles tendon injury that required surgery. Crawford, 31, played the season with the Portland Trail Blazers scoring 14 points per game.
The signing of Crawford means the Clippers will be cancelling their meeting with Ray Allen.
Just as a note, the Clippers are still operating without a general manager having lost Neil Olshey to the Blazers earlier in the offseason.
