Says Yahoo Sports:

Zach Ertz has a special mind-meld with Carson Wentz.

But Ertz quietly had a modest opportunity dip last year despite the Philly wideouts morphing into Spinal Tap drummers.

Forget if the Philly wideouts can play; if they can simply stay on the field (most of them), Ertz is a tricky bet into his age-30 season. With a juicy upside pool of tight ends (and some studs at the top of the queue), Ertz is essentially left in no-man’s land. I’ll root from afar in 2020, save for the occasional DFS punch.
