In order to truly be a complete team, the Celtics may need to upgrade their roster at the backup small forward position.

Big names like Shane Battier and Tayshaun Prince have been floated as potential candidates to be "this year's James Posey," but both may be too expensive to be realistic options for Danny Ainge to pursue.

Dennis and Callahan and guest Chris Mannix from Sports Illustrated, however, did come up with one name who may just be available: James Posey.

"The change in Frank Vogel to the head coach out there has totally made Posey irrelevant," Mannix said on the show, adding that Posey could request a buyout "if he continues to not play." Posey has played just four minutes since Jan. 31.

"It's possible he could wind up back in Boston," Mannix added.
