You make some valid points there. However, I believe Roethlisberger's struggles have a lot more to do w/ what he's gone through since the offseason than I do the running game. First of all, Parker is having a good season for them, so in general, the running game isn't the key factor to their losses. It does hurt them near the goal line or in short yardage situations, but they still have a capable running game overall. Secondly, it's gotta be tough to have a near fatal accident, an appendectomy, and then a concussion w/in a year's time and NOT be affected by it. Concussions are not something to be taken lightly, like a sprain or bruise. It's a brain injury w/ lasting effects. Don't believe me? Check out how guys like Al Toon and Merrill Hoge continue to suffer to this day due to concussions they had in their careers.
