The basis of his argument is this:
1) Eagles value QB, OL and DL at a much higher premium than all other positions.
2) There roster as it stands right now- QB is the weakest of those positions.
3) The draft is the strongest at the top at the QB position.
The likelihood that QB is the top player at a position they value the most at 6 is significantly higher than any other position.
The wildcard being under Sirianni, a WR coach by trade, will they put more of a premium on WR/pass catcher in which case Chase, Pitts, Waddle become more in play.
