Grisdale indeed!!! Senior D man in my first full time year of attending RPI Hockey in 1965-1966. Fortunately, dad brought me to a couple of games toward the end of the previous season when I actually got to see Senior Jerry Knightly play.All 5 on my list for certain. Have a few others to consider also - Adam Bartell, Patrick Rachon, Brad Layzell, Stepane Robitaille, Allen Kummu, and from the distant past, Bill Grisdale. Can't comment on the 1954 group and as has been said, really difficult to compare across decades of hockey. I submit though that any of these listed so far (if we could bring them back and add them) would make next year's squad quite formidable!!!!
However, Grisdale was a pair with another guy that should not be forgotten either despite the 65-66 team being pretty dreadful (3-19). Obviously, it got a little thin in the back after those two.
The other guy was Al Jones who, as a D man, actually led the 65-66 Engineers in scoring with 10 goals and 10 assists. There wasn't very much else up front either.
