Montreal Alouettes Sign Chad Johnson to a Two Year Deal

I'm still not sure whether signing these old NFL star receivers is a good idea for the league or not. I suppose that the Alouettes can get rid of him whenever they want (and I assume Johnson isn't broke enough that he couldn't quit whenever he felt like it), so the team should be allowed to do anything that makes the team better. I'm just not sure that the team is better today. At the least, he'll have a high percentage of getting injured at some point due to his age and break from playing competitive football.
