Putting his dreams of being an NBA executive on hold, Michael Finley reportedly is attempting a comeback in the league. The former NBA All-Star has been working out strenuously and is hoping to land one more contract to play in the league, according to ESPN.com, which cited sources close to Finely. Finley, 39, had been working with Dallas Mavericks president of basketball of operations Donnie Nelson to develop his front-office skills. He had convinced Mavs owner Mark Cuban that he had promise in the business side of the NBA. ESPN.com reported Finley received a non-guaranteed contract to participate in the Mavericks' camp in this fall, but suffered a calf injury. Finley is healthy now and is pitching himself to NBA teams for a playing contract. Finley played 15 seasons in the NBA, last playing with the Boston Celtics during the 2010 playoffs. He averaged 15.7 points a game and 4.4 rebounds.
