MSU's media guide lists a "Jim Doyle" scoring 5 goals in a
game vs. Ohio U. on 2/7/61. But the letterwinners section
says James Doyle, a defenseman, played in '50 and'51...and
scored only 2 goals in his career. The 5 goals in question
were apparently scored by Robert Doyle, a forward who
played from '61 to '63.
Not to disparage Gruden, who is a fine player, but some
verification would be nice. I believe Joe Bertagna at the
ECAC has access to lots of older hockey records.
