Zach Ertz

The Philadelphia Eagles locked down Zach Ertz.

The team announced the tight end inked a five-year contract extension on Monday, keeping him in Philadelphia through 2021.

NFL Media Insider Ian Rapoport reported that the extension is worth $42.5 million, with $20 million in guarantees, which makes Ertz the fourth-highest paid tight end in average and guaranteed money, per a source. Jimmy Graham ($10 million), Julius Thomas ($9.2 million) and Rob Gronkowski ($9 million) are the top three in average per year.

Ertz finished as the #10 TE in standard scoring, but was #6 after his Week 8 bye, averaging 6.4 catches for 73 yards and 0.25 TD (on 8.8 targets per game) in his final eight games. On the season, he racked up 75 catches for 853 yards and two scores. Given his size and relative catch radius, his touchdown rate should increase eventually. Playing time was the issue in his first two NFL seasons, but he played 72% of the snaps in 2015 and 79% in his last five games.
