No. I generally side with the player over the owner. Unless Dez is asking for a ridiculous amount that is not feasible (and I don't think he is), then I don't see why the Cowboys cannot get him a long term contract.
Jerry Jones and his entire family tree will never have to worry about going bankrupt. While a lot of NFL players have thrown away their fortune on silly stuff, the fact is that a high percentage of them have gone broke and the fact is that Jerry Jones and his family tree could spend more money on sillier stuff and they will never go broke.
The player has to get what they can. And the only things you deserve in life are the things you earn. And Dez has earned a new contract as far as I'm concerned. He might not deserve Calvin Johnson money, but I have no problem giving him the #2 WR in the league money.
The other issue is that it is a long standing, unwritten rule in the NFL that when a player has outplayed their contract that the team will make a good faith effort to get them a new contract that fits their performance. This is because the team should 'do right by the player' as they can cut the player virtually at any time and save themselves a lot of money.
Again...if they have unreasonable demands I can always understand the team's point of view. Otherwise, I side with the player.
