I guarantee you there are at least 5 people on this forum who are stronger in the weightroom than Bolt or Powell at lighter bodyweights. They would probably toss around their maxes like it was a warm-up. They will also lose by a second or more to them in the 100m despite the fact that they train for sprinting.
It is a little more complicated than just “get as strong as you can.” There are numerous 11.0 guys that don’t do that much/that intense of lifting that have better maxes and they still get shit on by those guys.
Yes, it is probably true there would be guys stronger yet slower than the elites. What seperates elites from the slower guys? Contact time and the amount of force they are applying through each contact(genetics):P
