Several, probably.
1. It's always best to hang on as long as you can to see what "shakes out" in the market.
2. If we'd really like to have him back (even as a backup), then it's best to let all the other teams spend their money before we release him. There will be no teams interested in him and so he comes crawling back and is willing to take backup money. (that's all he's worth) If he balks, let him retire or go somewhere else.
3. Where do you get the idea that we "owe" him something? This is business, pure and simple.
He's been VERY WELL compensated over the years by the Cowboys. Very well, indeed. I'm sure that he is pretty well "set for life" financially.
He wanted to "hold us up" for more money just a couple of years ago, and we let him go out and "test the waters" back then. I think he found out that he wasn't worth as much as he thought he was.
Didn't we re-do his deal anyway and get him some more money, just not the exhorbant amnount he was asking for? What has he given us in return? One fairly decent year, and one blah-blah year.
Better yet, what does he have to give us now? He can't get outside and make the blocks. We're gonna need a good running game this year if we're going anywhere. I think his pass protection has fallen way off, as well. He might survive another year (as a starter) if he is surrounded by great players. I don't see us having great players. We'll need to make do with "adequate" ones and he isn't quite adequate anymore.....
