I come down on Chrissy's side, although I'll reiterate my feeling that the coaches, athletic administration, conference officials...are all adults and drawing a salary so in that respect are all fair game (although I still support moderation and constructive criticism).
Where I have a problem is over-the-line negative commentary addressed to the student-athletes. Some people here (and it's more than one), and on the other board have convenient amnesia regarding comments like "horrible," "wasted scholarship," and other pleasantries directed at individual players. IMO, we should be better than that, especially on this board.
