I was only a few months old when this all went down but I was certain I read somewhere that the hit from LC is basically what began the end for Roger cause it helped lead to the second concussion he receieve, in a very short time frame, on that hit against the Rams.
I know there is even a story on one of the Americas Games for the Steelers where LC tells the story that the following season when Pittsburgh game to Dallas that Roger apparently told him that his kids hated LC cause he was the reason their dad had to retire.
