Former superstars Bobby Hull, Larry Csonka and Dave Parker have probably never been mentioned in the same article until now. But hockey's famous "Golden Jet," football's "Zonk" and baseball's "Cobra" actually shared several athletic traits that are now being recognized because of the discovery of a most unusual item used by all three of them.

First and foremost, these three special athletes possessed exceptional strength. Parker exhibited his power both at the plate and in the field. He combined 339 career home runs with a feared rifle of an arm from the right field corner. No one took an extra base on the "Cobra's" arm. Hull and Csonka were virtually unstoppable once they built up a head of steam on their respective playing surfaces. Once either Bobby or Larry were able to break free from the first line of defense they accelerated forward in the violent manner of a runaway train. Placed in this situation most defenders instinctively favored a "chase from behind" strategy over the more conventionally prescribed direct confrontation technique.
Durable is another trait that applies to all three of these men. They were noted for lengthy careers and their ability to play through injuries. Larry rarely missed a game although he suffered more than ten broken noses, multiple concussions and various other injuries on the gridiron. Likewise, Bobby seldom missed a game; often receiving his stitches right on the bench between his normal shifts on the ice. Dave was perennial driving force in the lineup and played for 19 seasons in the big leagues.
Hull and Csonka left their respective teams at the peak of their careers for more financially lucrative contracts offered by new teams in upstart rival leagues. After playing fifteen seasons for the Chicago Black Hawks of the NHL Bobby joined the Winnipeg Jets (so named after Bobby's nickname) of the WHL in 1972. Larry left the Miami Dolphins of the NFL after playing there for seven seasons and joined the Memphis Southmen of the WFL in 1975. Interestingly, both player eventually found their way back to their original leagues where they ended their careers and were elected to their respective sport's Hall of Fame's. After 11 outstanding seasons Parker left the small market Pittsburgh Pirates for bigger bucks also and played for five other major league teams before retiring in 1991.
These former superstars also share an unusual commonality for athletes playing in three different sports. Both Bobby and Dave, requiring unconventional equipment to protect their broken jaws while continuing to play, briefly wore football helmet facemasks identical to the style worn by Larry for most of his career. The facemask itself was unusual in that it was made from plastic coated aluminum rather than conventional steel. It was manufactured by Dungard Inc. and was listed as their "Running Back" model. Due to its lightweight aluminum frame it was an ideal choice to attach to Bobby's somewhat meager hockey helmet and Dave's dual earflap (with retrofitted chinstrap) batting helmet. 
Bobby Hull, Larry Csonka and Dave Parker were icons in their respective athletic careers. Despite sharing the aforementioned physical characteristics and financial motivations their unique playing styles have never been previously linked together until now. With a tip of the hat to those special readers of Helmet Hut, all it took was the recognition of a very rare and special aluminum football helmet facemask.
