Brandon Jennings has a new back up, as the Journal Sentinel reports; “The Milwaukee Bucks continued to fine-tune their roster Monday by signing veteran free-agent point guard Keyon Dooling. The Bucks used their bi-annual exception to sign Dooling, 30, to a two-year contract worth about $2 million per season. Both years are guaranteed … The 6-foot-3, 195-pound Dooling has played in 595 games for four teams over 10 seasons. ‘Keyon is a veteran and will complement Brandon (Jennings),’ Hammond said. ‘He’s filled both roles as a point guard as he’s been a starter in the NBA, and he’s played a backup position. He’ll fill in for Brandon with a little added size. Keyon is tremendously long at 6-3 and has always been known as one of the better on-ball defenders in the league.”‘
