Concussions are a scary thing, for me it took 3 week to get rid of that foggy headed feeling. It's a feeling were you have trouble focusing on what you are doing and multitasking is harder to do also. Shady has lost a step and he is going to start breaking down. I also think that concussion is messing with him mentally, I think he might have another solid season in him but it's not worth the money to find that out.
