I'd like to defend a fan's right to criticize a player/players. If players don't want to be criticized, then they have two options: 1) don't play in the SEC or 2) don't suck. SEC sports (and D1 sports period) is just a step below the pay for play leagues. Consider it training for what will happen if you do get lucky enough to get paid for what you do.
If players are sensitive to criticism, I suggest playing D-2 sports and working on a degree in something, or just quit sports and work on your degree, because they obviously can't handle what it would take to continue playing for pay.
When Papelbon blows a save in Boston, I'll bet he doesn't receive a pat on the back and a "you'll get em next time" from Red Sox fans. Players get criticized for not making plays. That's just the way it goes.
