Rob Gronkowski has dominated the tight end rankings in recent years, often described as being in a tier of his own.

In 2015, Gronkowski was once again was of the most productive players at the tight end position, but we saw a number of new and old faces emerge and have productive seasons this year.

Tyler Eifert predictably broke out as an elite red zone option for the Bengals after missing nearly all of last season with a dislocated elbow, but who saw Gary Barnidge emerging as the go-to option in the Browns' passing attack? Or Benjamin Watson revitalizing his career with Drew Brees in the Big Easy?

All of these tight ends had great seasons, but were any enough to knock Gronkowski from the top spot?

Let’s take a look via numberFire's Reception Net Expected Points (NEP) metric to find out which tight end had the best season in terms of adding points to his team above expectation level.
