This is Steve McNair the article is about. The guy was an injury waiting to happen, playing in an era where you cannot hit a QB, and he constantly missed games and/or started games and came out within the first couple plays. Tough, not even close.
It is very obvious that you don’t know much about the game and how Steve McNair played it. If you did, you would know better.
Take this from me, a former collegiate player....McNair was tougher than any QB in the game. He did not just sit back in the pocket. He ran the ball, blocked, and threw the ball. It was unbelievable how much punishment he dealt out and received and still played on.
