Agreed.
As dominating as Koss was at Lillehammer, there was no way he could win the 500 meters AND the 10 000.
Heiden - all time legend.
In their coverage of Heiden's last gold medal race, one of the major U.S. newspapers (I think it was the Washington Post) referred to Heiden as "the Secretariat of speedskating." I can't think of a better description of an athlete that dominated his sport the way nobody else has ever done.
