Five factors that could impede the move of the Seattle SuperSonics to Oklahoma City, with analysis by The Oklahoman's Berry Tramel: •New arena in Seattle: Though the Oct. 31 deadline for a new arena deal has passed, chairman Clay Bennett would be hard-pressed to turn down a state-of-the-art building if something develops in Greater Seattle. Chances: slim. Where is the momentum to build an arena? •Sell Sonics: A group of Seattle businessmen have offered to buy the NBA Sonics and WNBA Storm from the Oklahoma City group. Chances: slim. The NBA ownership club is difficult to enter; Bennett has enjoyed being part of the NBA, and his partners back in Oklahoma City are anticipating bringing a franchise to their hometown. •Court rules for Seattle: The Sonics were denied the shortcut of taking the lease disagreement to arbitration, so now a federal court will decide if the Sonics can break their KeyArena lease. Chances: strong. The court likely will rule in favor of Seattle, that the Sonics must fulfill the lease with their presence, not with a cash payout. •Negotiations stall: Without court approval, Bennett and Co. must negotiate their way out of the lease if they want to leave before summer 2010. Both sides have strong bargaining chips. The Sonics will hemorrhage money as a lameduck team; but the Sonics also can offer to leave the team's name and history behind, if allowed to move. Chances: moderate. Both sides have much to gain and much to lose. •NBA withholds approval: To move, the Sonics need approval from a majority of a relocation committee, made up of owners appointed by commissioner David Stern. Chances: slim. The owners generally follow the lead of commissioner David Stern, who seems firmly in Bennett's corner, with critical remarks both a couple of years ago and recently that Seattle has not produced a viable arena plan.
