You could argue that the Eagles had the best RB, the best OL, and a top 5 WR duo in the league this past season.
With all that being the case, Hurts was 20th in the league in passing yards (didn't even break 3,000!) and 21st in passing TD's (18, barely even 1 per game).
He's basically half average passer, half very good RB, and once those legs go, he's going to be horrendous. He's never even broken 4,000 yards passing or 25 passing TD's despite playing 17 games.
The Eagles could've gotten the same or similar passing production out of at least 15-20 QB's.
