While I understand the wish that every competitor be a slouch, so that we can run up the win column, a la Memphis, it is actually in our interest to have a strong conference. To use the most obvious example, every year in the ACC, there are 6-8 teams considered NCAA tourney caliber before the season even starts. ACC games are beamed nationwide every week. Players know that they will be seen if they play in the ACC, even if they do not play for Duke or Carolina.
Gillispie going to OSU would be a net gain for Big 12 competitiveness and exposure. The games would be more likely to be shown nationally, helping A&M and the rest of the conference recruit the top athletes. Big 12 teams, having been toughened by the games within conference, will compete more effectively in March. You don't get better playing inferior competition.
While I don't hope for Gillispie to get fired and come to OSU, I am not afraid of it, either. It would just be one more great matchup in Big 12 play, to go along with KU, tu, OU, Tech and now, Baylor, Missouri and K State.
