It s quite an accomplishment to be the all-time hit leader, but I agree with your comment about average. Also, I would expect a lead-off hitter to be the all-time leader in number of hits, since they would have the most number of opportunities.
Pirmin Zurbriggen was the top FIS skier of all time, in my humble opinion. His 40 wins in FIS races is a distant seventh on the all-time list among men, but he won races in every discipline, won four all-around World Cup titles, and only competed for nine years before he retired in his prime at the young age of 27.
