If you think back to his Bears days, Harbaugh was a pretty tough dude too. Either that or real stupid. He got creamed on every single play like the lineman had found out he slept with their wives and he kept getting back up. It was really hard to watch. A new nominee has arisen, coincidentally from the Bears as well ( a one time deal). Muhammed took a mean shot on his TD catch last week (by Dre Bly, I think?) and got shoved into another defender (Bryant maybe?) , who is now likely out for the year! That's tough!
