By David Aldridge Special to ESPN.com About six years ago, I wrote a column predicting that the next great class of free agents would come in the summer of 2003, when guys like Gary Payton, Alonzo Mourning, Juwan Howard and others were completing their (then) just-signed contracts. I remember getting an e-mail response from a guy who thought I was nuts, that the aforementioned men would be talent-stripped geezers by that time. Well, here comes Summer '03, and it's the old guys that give this free-agent class some pizzazz. No diss to J Kidd, but his is a three-team derby between incumbent New Jersey, San Antonio and Dallas -- three of the NBA's final four teams. It's a battle of the haves and the haves, a fight in rarified air. Kidd's destination will shift the balance of power, but only a little. The Nets and Spurs just played each other in the Finals, and the Mavericks were two wins short of getting there. If Dallas and San Antonio don't wind up with the game's best point, it's not like they won't have a chance next season. (The same can't be said for the Nets; a Kidd departure would devastate their future.)
