The difference between Josh carrying the offense this season or not wasn't going to be a 6th round pick. When was the last time a 6th round pick WR made a meaningful impact their rookie season? Has one ever? Antonio Brown (6th round) obviously became elite, but his rookie season was very meh. Puka Nacua had an incredible rookie season as a 5th round pick and Amon Ra St. Brown did as a 4th round pick, but it is incredibly rare.
