3. Randall Cobb, WR
Let's just preface this by saying that Randall Cobb has had a solid NFL career so far. A former 2011 second-round pick out of Kentucky, Cobb has gone on to record over 7,600 yards with 54 touchdowns in 166 career games, even making the Pro Bowl once. That's a better career than most.
The 33-year-old was signed by the Jets last offseason in an attempt to make Rodgers feel more comfortable. The wideout-quarterback duo spent 10 seasons together on the Green Bay Packers, after all. Having said that, Cobb is no longer the player he once was and it's time to let him walk as a free agent this offseason.
Appearing in 11 games last season, Cobb finished with a career-worst performance of 39 yards and one touchdown on five receptions. His 29.4% catch rate and 19.6 passer rating when targeted were also personal worsts. To put things into perspective, a QB would have a 39.6 passer rating if he only threw the ball into the ground for four quarters.
I get that Rodgers and Cobb are buddies, but Douglas needs to put his foot down and show Cobb the door. The Maryville, TN native just isn't a player who brings the Jets closer to a Super Bowl. He can either try turning his career around elsewhere or even consider retirement.
