Tough to say, reag, I simply don't know. Maybe the sport was de-emphasized? Maybe the great in-state players decided AZ or FL was a better place to play? I know the current regime (well, the one right before this one anyway) saw fit to build a beautiful baseball-only stadium on campus, so maybe that's turning around.
