My thng with Ertz is that I dont think its a coincidence the Eagles have gotten a bit more explosive without him. Goedert is the better blocker and downfield/yac threat. Ertz like AJ will be better with a true #1 WR on the team. Maxx really did a lot for the team those first 5 games. He was like a poor mans Kittle (for 5 games) tbh.
Too many variables. The reason the Eagles traded Zach is they knew they were getting Goedert back soon and it was apparent to them that Hurts will NOT throw over the middle so paying 2 TE's big money made no sense.
Since we got Zach he has 49 catches, in 10 games 490 yards (if my math is right) so basically 5 catches a game for 10 YPC. 3 TD's. We got Zach the first 2 games he was great and learning the offense, the 3rd game we had no Kyler, no D Hop and Edmonds got hurt on the first play of the game. Since then we have not had the whole offense together so you can't really compare the offense with Maxx to the offense with Zach and say that's the problem, there's TONS of other guys missing too.
Since the Eagles traded him Goedert has 41 catches for 614 yards so 15 YPC and 2 TD's. The Eagles changed the offense after the trade they went to a run heavy package where they really only throw to 2 guys, Smith and Goedert, often play action. Both of them have seen their YPC go way up since the change because everyone is playing to stop their run game. So the Eagles have CLEARLY gotten better but I don't think it's because they got rid of Zach it's because they accepted that it made no sense to have 2 good pass catching TE's with Jalen Hurts. To his credit Hurts has figured out how to use Goedert, the biggest complaint about him as a QB is he won't throw over the middle, he's started to do that. They just decided asking Hurts to run an "NFL" offense wasn't working so they modified to be more like what he did in college and its' worked, it just has limits.
It worked out well for both teams, Goedert has taken off since the trade, and Zach has been a godsend for us.
