I think if this year has taught us anything, it's that we need to be deep at WR. Injuries killed us at this position. So I would hope the Packers carry 6 next year. With this teams injury luck, you can pretty much bank that our 6th receiver will need to play a role. So with that said I'm in agreement with most here on who to keep:
Nelson, Cobb, Janis, Montgomery, Adams, and Abbredaris.
As much as I loved Jones this year, it's just hard to see how we make room to bring him back unless a trade is made. Montgomery showed a ton of potential early on this year, and our offensive struggles really became pronounced once he went down. I think he'll be in the mix, and Im not ready to give up on Adams quite yet either. Janis looks like a legit deep threat. Cobb and Nelson are already proven.
I'm actually rather excited about our receiver group next year if they can stay relatively healthy.
