It absolutely has been in GB. So it’s not a myth here.
I'll disagree....with some sure, BUT one must dig deeper than surface. Often times this has been the case in Green Bay solely due to the depth chart ahead of them. Let's discuss the 5 or 6 most recent successful cases of Jennings, Nelson, Jones, Cobb and Adams...the 5 most recent successful and drafted by us WRs we have:
Jennings (06'): Only clear guy ahead of him was Driver. 2006 drafted, closed that season with 632 yards - 45 receptions and 3 touchdowns.
Jones (07'): His first year (2007) the dude started 9 games and garnered 676 yards - 47 receptions and 2 touchdowns. Dude delivered early.
Nelson (08'): Was firmly behind Driver and Jennings and James Jones a year prior as a rookie had stacked up an AWESOME rookie year...and a strong TE group that took targets away. Wasn't until year 4 that he was able to garner more targets. However, as a rookie he was consistent when asked - 366 Yards - 33 receptions and two touchdowns.
Cobb (11'): Drafted in 2011 and OUT THE GATE delivered as he could. He was FIRMLY behind Driver, Jennings, Jones, Nelson and Finley(TE) he still somehow produced BIG numbers on special teams (over 1200 yards and 2 TDs) on offense still produced 375 yards - 25 receptions and 1 TD
Adams (14'): Drafted and behind Cobb and Nelson clearly, while everyone wondered if 2013 and Boykin's performance was legit or could Adams push to the #3 quickly. Adams put forth SOLID rookie numbers at 446 yards on 38 receptions and 3 touchdowns once he earned time and never looked back.
Now a few others that saw success early but we don't know future progression or sustainability:
MVS (18') - 3rd on the team in receptions...finished his rookie year with 581 yards - 38 receptions and 2 TDs
EQ (18') - In basically the last quarter of the season he put up awesome numbers with 328 yards and 21 receptions
Few memorable guys that arguably fit the "took a while to flourish"
Ferguson - I remember thinking he was going to progress into the second coming of Antonio Freeman...had a great 3rd season and then just fizzled out.
**Javon Walker - Honestly should have been included in the first group but his career just isn't as good...talk about BOOM and then nothing. His first year he was the #3, and then arguably our 2nd best WR...so another that showed early he could produce.
