Tony Dorsett, Joe DeLamielleure (played with O.J.) and Leonard Marshall all took the test and have symptoms.
Watch this video of Dorsett. Fans of my generation loved this player. Lot's of guys wanted to be Tony Dorsett. Just like MLB has PED, NFL has CTE; this is altering the way that this physical sport is played. What a shame.
