"Hayman suffered a broken leg in the fourth period of the Oakland game and was sidelined for the remainder of the season. He was playing in relief of a hobbled O.J. Simpson at the time he was injured. Hayman carried seven times against the Raiders for 31 yards and a 4.1 average.
He moved from wide receiver, where he played in college, to running back during the preseason and showed excellent instincts as a runner. Gary will get a long look in the new position during training camp. He had two punt returns for 13 yards in 1974.
Gary was the nation's leading punt returner in 1973. He logged 23 returns for 442 yards, an average of 19.2, and one touchdown. Gary also led Nittany Lions pass receivers with 30 catches. He has played both tailback and flanker. He missed both the 1970 and 1971 seasons.
Gary is a political science major with an eye toward a law degree. He worked for a Buffalo employment agency during the off-season."
