As a fan, I hate when they do it. But I can completely understand it, when they outplay their contract. Not saying it's Revis' case, but take a look at LaMar Woodley. He's scheduled to make 500k this year. he's arguably a top 5 pass rusher, he's making less than Poppinga, and he has all the right to complain. He has complained, but not held out, though. The Steelers, like the Packers, reward their own, so Woodley knows he's gonna get paid. He could be hurt before it though, and get the short end of the stick, when he was a key cog in winning a SB, and generating tons of revenue, which he saw nothing of.
