In alot of ways Mike epitomized the fun part of the bodybuilding lifestyle, ie you can see from his demeanour, posing, interviews that he seemed to really soak it in, he also was one of the first of the top pros of the 90's to show the downside of the whole thing
I don't feel his bodyparts were really "weak" as much as his stronger ones(delts, arms, abs, calves) just overshadowed the other ones
The guy had a good back, chest and legs, they were just overshadowed IMO
