Stash, don't discount the fact that Cobb was dealing with a nagging hamstring most of the season last year (the only game he was truly healthy was week one, I believe, when he tore the Bears a new one).
In 2017 when he was healthy most of the season (mostly with Brett Hundley throwing him the ball) he still had 66 catches for 653 yards and 4 TDs in 15 games.
Packers threw the ball 562 times in 2017.
Cole Beasley for instance, had 65 catches for 672 yards and 3 TDs in 16 games last year.
Cowboys threw the ball 527 times last year.
Cobb can play outside or inside which Beasley can't.
Not dogging Beasley and not trying to tell you what to think, just sharing my thoughts.
