You could almost hear the briefcase clicking shut Monday evening.

That's when Howie Roseman finished a four-month negotiation with Fletcher Cox, perhaps already the best defensive tackle in Eagles history and probably the best athlete in the city, depending on how you regard Claude Giroux.

According to ESPN, Cox, 25, agreed to a six-year, $103 million contract extension, $63 million of it guaranteed in various manners. It might turn out to be the most guaranteed money a non-quarterback has ever made, but NFL contracts are specious documents full of misdirection and hidden intent. That doesn't matter.

It also doesn't matter that the Eagles clearly blinked. Cox missed the voluntary portion of the offseason and seemed prepared to hold out of training camp, too. With a new coaching staff, his absences so far will mean he will need to catch up when training camp starts July 25.
