I don't know if I like paying a WR this much either. I am however tired of hearing that "no" receiver is worth this much. Dez Bryant doesn't just contribute to the Cowboys winning games, he flat out wins them sometimes. He is a player that transcends silly cliches like "no receiver is worth x amount".
I don't know if he is worth 15 million a year, but I do know you can't apply linear logic to his contract. Like Romo, he can win games you flat out aren't suppose to. Yes, you can argue that redistributing his money in order to make the team more balanced is indeed a better option, but don't delude yourself into thinking that 2 good receivers is somehow better than one great receiver. Witten is a good receiver, Williams is a good receiver, and most of the free agents we could snag are good receivers. Do any of those "good" receivers catch even 10% of the catches worthy of making it into a Dez Bryant highlight reel? How valuable are those catches anyways (no seriously, that's the argument isn't it)?
I think we saw the value of the catches Dez can make in the playoffs and leading up to the playoffs. Good receivers don't always make those catches, and neither does Dez, but that 15 million isn't just getting you a few hundred more yards a year and a few more touchdowns, it is getting you something much harder to put value on.
I have confidence in Dez performing as a super star for the Cowboys, as I'm sure everyone of you does as well. Please compare that to the confidence you have in the Cowboys (or any team) effectively redistributing that money into free agency. I'm betting on Dez, and up until this point anyone who has bet against him has been wrong.
