Big 12 - Pac10 Challenge forthcoming?

Looks like we could see that as soon as 2007.

Big 12 vs. Pac-10 challenge in works

The Big 12 and Pac-10 are continuing to discuss a possible early-season basketball series, similar to the ACC-Big Ten Challenge, that might debut in the 2007-08 season.

Officials from the leagues are exploring playing 12 games over four days in late November or early December. Since the Big 12 has two more teams, two Pac-10 teams would play two games, one at home and one on the road.

"There is interest on both sides in moving this forward," Burda said.
