I'd be surprised if Shakir doesn't take advantage of this opportunity. With Hines taking over and doing a great job as the returner, McKenzie doesn't even have that to protect his job.
I believe Beasley is still under contract and he should return in a backup role, maybe 66% Shakir, 33% Beasley, to keep him healthy for the playoffs. Crowder I'd only bring back at vet minimum and use him sparingly if so. He's unfortunately made of glass.
Then again, Von said OBJ would be a Bill ...
