Why would this be The Concussion Blog news?  Well, its more of a theory and observation than news, just stick with me here…

In 2008, Edwards was a very good quarterback for the Bills, and progressing well, until this hit by Adrian Wilson, then of the Arizona Cardinals.

Edwards was never the same after that hit and now he is looking for work.
