Philadelphia Eagles tight ends coach Ted Williams has tipped second-year Zach Ertz to post huge figures in the upcoming campaign.
Ertz posted 36 receptions during his rookie campaign last year, with 469 yards and four touchdowns to his name.
Williams now expects Ertz to build on those numbers, with the coach praising the skills which the protege has shown during pre-season.
He told the Philadelphia Daily News: "You knew when you watched Zach in college that he had the chance to be something special.
"Honestly, he's one of the best route-runners I've ever seen. He takes a lot of pride in that.
"He has a lot of confidence. And he's hard to defeat, because he doesn't take defeat very well."
Though not the quickest, Ertz's reading of the game has been praised by many, with NFL Fantasy Football tipping him for a 60-catch, 850-yard season.
