For the most part, NFL players have been pampered and spoiled throughout their entire life. They were always the special ones in high school, the girls loved them, the teachers took it easy on them, if they even bothered to go to class they hung out with the cool guys, no one messed with them. They were wined and dined in high school by colleges trying to get them to attend. When they went to college, most of them didn't even have to crack a book let alone pay a cent to go to schools that would usually cost closing in on $50k a year. They were once again wined and dined and given those special presents that we weren't supposed to find out about.
Next they find themselves drafted into the nfl getting paid millions of dollars a year. Fans love them, people pay them money just to show up and say hi, they get flown all over the world by people that just want to hang out with them.
Now they wake up, and for the first time in many of their young lives they are being told "no" They aren't being paid, they aren't getting what they want, they expected all the fans to scream for them to come back, but not everyone is. Sure their buddies, the sportscasters are siding with them, because they have to, but lots of fans are siding with the owners. That 3 million dollar house has that pesky mortgage and those damn property taxes, let alone the health care for their wives and kids.
It must be a huge shock to some of these players, and they are upset, and lets face it scared a bit, and mad, and whatever else. Many of them aren't very bright to begin with, and football is all they have ever known.
Unless it is settled soon it will just get worse and worse for the players. More and more of them will make stupid comments because they aren't being asked what Sunday's opponent will have to do to stop them. They are being asked tough questions, questions they have never been asked before.
