Meeks has agreed to a $19.5 million, three-year deal with Detroit, a person familiar with the situation said Tuesday night. The person, who spoke to The Associated Press on condition of anonymity because free agents cant sign contracts until the leagues moratorium ends July 10, also said Cartier Martin had agreed to a one-year contract with the rebuilding franchise. The 6-foot-4 Meeks averaged a career-high 15.7 points and scored a team-high 1,209 points last season for the Los Angeles Lakers. The shooting guard has averaged 9.7 points over his five-year career. Milwaukee drafted Meeks in the second round in 2009 and traded him during his rookie season to Philadelphia. The Lakers signed him as a free agent in 2012 and exercised a team option last year to keep him on the roster for a second season. Martin, a 6-7 small forward, has averagged 5. Matt Miazga Jersey . 4 points over his six-year career. Earlier on Tuesday, when NBA free agency began, the Pistons announced assistant general manager George David was stepping down. David was a part of the previous front office that was led by president of basketball operations Joe Dumars. The Pistons hired Stan Van Gundy in May to replace Dumars and to also lead them as their coach. Van Gundys first major move appears to be adding Meeks. The Pistons, who havent earned a spot in the playoffs since 2009, are trying to reshape their roster to make the most of 20-year-old centre Andre Drummond. They probably will be relegated to keeping forward Josh Smith, who signed a $54 million, four-year deal last summer, and point guard Brandon Jennings, entering the second year of his $24 million, three-year contract. Detroit does not know if it restricted free agent Greg Monroe will be back. ___ Connect with Larry Lage at www.Twitter.com/larrylage ' ' '
