In the early WSM's the guys were big, and as it progressed, bigger and bigger men have appeared over the years
Pudzi and savickas are so different physically and not the biggest guys in the competition, yet both are past winners
Geoff capes was large, but fat, virtaenen was considered "skinny" (not my words), etc
Kaz was 6'3" 330-350lbs ? Shaw is 6'8" ± 415lbs
I think kazmaier would still do well. Physically and mentally strong
