I should clarify that my 'no' was more in reference to Barry's insistence on (IMO) misinterpreting Weyand's data to suggest that sprinting mechanics are not important. I was not attempting to say that mass-specific force is not the most important factor, just that I strongly disagree with how Barry interprets it. For instance, ignoring (despite his insistence that he doesn't) the vector of the force application is completely wrong. Barry seems to be almost completely centered around increasing strength-to-body weight ratios in a very area specific area (deadlifts). I think that this is only one component of sprinting performance. If increasing strength-to-bodyweight ratio in one lift, the deadlift (Barry's primary indicator and training tool for training MSF), was all it took to be fast, elite powerlifters in the light weight classes with the best deadlifts would also be the fastest people in the world. Most recognize they aren't even the fastest athletes in strength sports (elite OLs are likely much faster).
