Don Hilgenberg&NFL
From Don Hilgenberg we now know the Hilgenbergs played in the NFL. Wally (number 58) played linebacker for the Vikings in the late 60’s, early 70’s. Wally was in the Super Bowl when the Viking’s played the Dolphins (He thinks it was ‘72, the Dolphin’s team with Csonka and Mercury Morris in the backfield).
He says Jay started as center for Chicago in the Ditka era, when McMahon was QB and the ‘fridge was playing. But he doesn’t think that Joel ever played a prominent part on any team, but was definitely on a few rosters. Jay was traded (or exiled) to Cleveland, and he believes that he finished his career there.
