When the Green Bay Packers drafted Ty Montgomery in 2015 he was considered the heir apparent in the slot for Randall Cobb. Then the injury-plagued backfield necessitated him to switch positions.
Now, moving on from Cobb is not as pressing as what the internet in general would have you believe. I actually think the Pack will restructure Jordy Nelson (two years/$15 million) if they can extend him a year and let Cobb play out his contract.
However if the Packers do move on here is a possible solution.
