What a tool.
Simply not true. There are two primary factors in "strenght", taking leverage and technique aside. Mass and nervous wiring. You can cause hypertrophy and add mass, but still be held back by your inhibitiors, kinetics chains, motor patterns and nerve endings. Just like you can improve those factors without gaining much mass(which is basicly what most newbie gains are).
Co-ordination between muscles are also equally or more important than pure strenght in any physical activity that takes skill. Which is basicly any sport. That is why someone who is good at oly lifting will be able to clean and jerk more than a powerlifter, but strict press less. Powerlifting is part skill as well don't get me wrong(or at least correct motorn patterns are very important), but they are different. The oly lifters applied or "functional"(I dislike the word too) strenght in this case will be greater given the task, while his absolute strenght will be lower. It's not just about leverage, it's about co-ordination, explosiveness and nervous wiring.
Point is strenght is not just strenght and that there are different kinds of strenght. Also mass is only part of strenght. Everything is in relations to the task. Luckely a lot of it intertwines so you can definitely gain something from a proper S&C program.
I'd say that the BB's mass and strenght helped him absolutely none in this fight.
