Wow...
Don't worry about what people say about you? When you were 21 years old, how would you have felt if an entire STATE was telling you that you sucked (whether it was in person, on message boards, or on sports talk shows)?
If this were a professional football team, I would agree with you...shut up and do your job and let the fans say what they're going to say. But give me a break. These are kids who are playing football, getting an education, and not getting paid for it. Yeah, they get a full ride scholarship, but that doesn't mean that they have to be perfect! If you think that these players are just "coasting" and taking it easy then you have never been around a collegete athlete for any amount of time. It is not a glamourous lifestyle, especially when people who don't know what they're talking about are criticizing them every day.
Do people who don't work with you tell you daily at your job that you're terrible, working half-@$$ed, and should leave? I didn't think so...
You wanna blame the coaching staff? Fine. They are paid millions of dollars to coach these players, make them better, and produce results. These guys obviously aren't doing that. But don't blame the infantry when its the General who's really the problem...
