Again it's too early to know. Ertz has to feel great getting out of Philly when he did. He was being wasted there because of Hurts. Look at last week one game with Minshew at QB their offense completely opened up because they had a guy who can throw over the middle. Ertz has to realize how good he has it in Arizona.
We have an elite QB, an elite WR, several good other Wr's, a good OL, 2 good RB's neither of him figure to break the bank money wise. Ertz was the missing piece when Maxx went down and he's too smart not to realize that.
He's been there before with Philly when they were good he knows what it's like and he has to see all the pieces are there on offense. The defense is a bit older but still very good, very talented and has some guys who are becoming good players. He has to see that it's a good situation and maybe he'll want to come back for more and be willing to not try and break the bank to do so.
