The Packers will probably roll 7 deep at WR this year. 8 if you count Allison. Plus they should have a quality prospect or two on the practice squad. With Adams looking to break out as our #1 and Cobb being a legit 2...... Plus Allison is coming back and looks to be improved from an already good rookie year. So three legit guys we know can catch passes. Then we have a ton of good prospects who are running good routes and catching the ball......
At some point it's time to move on. Honestly, I could see Nelson traded now for a pick or very probably let go after this year.
