Clay Harbor, formerly of the Eagles and Jaguars, inked a two-year deal with the Pats in the spring, receiving a reported $400,000 signing bonus. That's a hefty guarantee for a player that is not considered a lock to make the final roster.
Or perhaps the Pats truly do have a spot set aside for Harbor. After all, he gives them something different.
While Gronkowski and Bennett have, as Bill Belichick said, "interchangeable" skill sets, the 6-foot-2 Harbor is in the "move" tight end mold: athletic and agile with the ball in his hands, able to serve as a fullback, and able to line up wide.
