It's possible that 31 goals is a professional hockey record. (Yes, the EHL was technically "amateur", but the players were paid and it was part of the NHL farm system.) I haven't found any larger score in any professional leagues, but minor leagues come and go and records are lost or hard to find. I also believe Tim McCormick's record 12 point night still stands across hockey. It's also possible that Reg Meserve's 4 minor penalties in the third period would at least tie a Devils' team record.
One of the problems of pasting together EHL history is that often hometown newspapers didn't publish on Sunday back then. The Camden Courier-Post, the Jersey Devils home paper was no exception. Since there was usually a Sunday game as well, Saturday's game many times scarcely got a mention and rarely a box score or picture in the Monday paper. In the case of the February 26, 1968 Camden Courier-Post it was also inaccurate as according to the box score, Gordie Stratton had 5 goals and only 1 assist, instead of the 5 goals and 5 asists the article states. Stratton's inaccurate total would have beaten the previous EHL record of 9 points in a game, set by Bill Purcell of the Baltimore Clippers in 1948. Note also that the Devils got shut out by New Haven loaner goalie Roger Wilson 6-0 the next night in spite of 43 shots on goal. Syracuse lost to the Johnstown Jets 11-4 on Sunday.
This game only tied a goal scoring record for Jersey. The Devils also scored 16 goals in a 16-7 victory over Jacksonville on January 19, 1965. The 23 combined goals is the largest previous EHL score I'm aware of.
Here's the scoring breakdown for the 16-15 game...
The one thing I've gained from trying to write about this amazing game is the need for centralized minor league hockey records. I personally need to create a Team and League Records page at http://TheEHL.com . This also shows that historical record keeping is not static, but ever changing during a league's run. It's just as important to know what the records are for, in this case, February 23, 1968 as they are for after the league has ended.
Discuss the game further with Syracuse forward (and former Devil) Wayne Caufield and other EHL players and fans at the Eastern Hockey League Facebook Group.
