Shaquille O'Neal's first choice is to join the San Antonio Spurs for one final run at a fifth NBA title, and he wants to play two more seasons before retiring, a source told FanHouse on Wednesday. The source spent time Wednesday with O'Neal in the Orlando area, where the legendary free-agent center makes his offseason home. The source said O'Neal said the Spurs and Atlanta are at the top of his list since there is interest with those teams on both sides. FanHouse's Tim Povtak reported Monday the link between O'Neal and the Hawks, and there were indications from San Antonio on Wednesday that the Spurs do indeed have interest. O'Neal also is interested in Boston but the source said he realizes the Celtics don't have much interest in him. NBA Fanhouse
