What worries me about that is I am guessing there are many BYU players that Ah You hangs out with. My guess is drinking is pretty common place among many on the team (based on this and other things that have happened). This makes me sad.
I don't think drinking is the worst thing in the world, but for players who both represent the University and just recently represented the Lord on a mission it makes me extremely sad.
Maybe it is better for BYU to be without sports? I have fought tooth and nail my entire life against that, but perhaps there is some wisdom in it.
