Crowell would be a good backup at all 3 positions.
He makes a lot of tackles but is not a playmaker.
The Bills need to add more play makers.
Adding Mithcell as insurance is what the Bills should have done at WR.
Patch the hole and then be free to draft a young stud if the opportunity presents itself - not force yourself to reach for a player
In any event, the Bills need LBs since both Stamer, Coy wire and Hagan are all gone from last year.
