PAC12..... The "Conference of Champions," the Pac-12 has won more NCAA National Team Championships than any other conference in history; the three schools with the most NCAA team championships belong to the Pac-12 (UCLA, Stanford and USC, in that order). With Arizona State's softball title in 2011, the conference won its 400th NCAA Championship.
Although impressive, that's not a very fair statistic due to the Pac schools having more sports. Sports like Water Polo aren't played east of the Rockies. Tennis, golf, swimming and diving are also predominately west with collegiate sports. Softball was also a historically west coast sport.
What's odd is after the top 3 Pac schools, little Abilene Christian is 4th with Oklahoma State 5th.
If you stop responding to them or put them on ignore, then eventually they'll go away.
