of course they were, but the narrative here is that they suck.
Matthews has caught as WR 1 in Philadelphia, 85 passes from Bradford & Sanchez in 2015 and 73 passes from rookie Wentz in 2016. Granted, the total yardage could be better (11.7 YPR), but the guy can and does get open. it's just a matter of throwing him the ball.
He was never their #1 target.
