It is rumored that the PAC 10 will offer spots in a conference of 16 to 6 big twelve schools. Those schools are Texas, Texas A&M, Texas Tech, Oklahoma, OSU and Colorado.
I think would improve all of the sports in the Pac 10, wrestling would aided by the addition of Ok and Ok state. Football would get a big boost from nearly every school except colorado and A&M, this would make the Pac the second best football conference after the SEC. Baseball where I think the Pac was already strong would benefit from the texas and oklahoma schools as well. This would create a power conference in nearly all sports. Good for the Pac bad for the Big 12 and possibly bad for the big 10.
