That is where the normalcy ended.
It appears that they had filed the Welker contract and it made the Broncos go over the cap. So instead of being able to file the reduction in salary with Dumervil they had to outright release Dumervil.
Stupid move Broncos because there are teams who are going to jump at the chance to sign Dumervil and don’t be surprised if Belichick decided to try to add him asap before Denver can clear enough space to get him back.
EDIT: It seems that this was the fault of the Agent for not faxing the signed restructured contract in time to prevent a cut. So thanks to the Agent screwing up looks like Dumervil has to start looking for a new place to sign.
