Cleveland Browns Hall of Famer Gene Hickerson died Monday at the age of 73. He blocked for three other Hall of Famers -- Jim Brown, Leroy Kelly and Bobby Mitchell. Brown was quoted as calling Hickerson “the greatest downfield blocker in the history of pro football.” Hickerson was inducted into the Hall in 2007 when Brown, Kelly and Mitchell pushed Hickerson's wheelchair onto the stage in Canton. Hickerson played in the NFL for 15 seasons, all with the Browns. He was a sixth round draft choice out of Mississippi. He was inducted into the Hall with Michael Irvin, Thurman Thomas, Charlie Sanders, Bruce Matthews and Roger Wehrli.
