Nelson, Cobb, Adams, Montgomery is no worse than Jennings, Driver, Cobb, Jones
Jones was never great when he was with the Packers. Adams had as many or more catches in his second year (50) as James Jones had in any of his first 5.
Nelson has had some incredible years that are better statistically than Jennings or Driver.
Cobb has had several really good years too. As good as Jennings or Drivers better years.
Yes Monty is a relatively unknown but he sure looked good while in there. In 4 and 1/2 games he had 15 receptions on 18 targets.
Last year was awful for the WR group as far as injuries go and one has to hope it was an anomaly.
