Nothing too controversial there. His implication that "strength quickly" is King needs a bit of fleshing-out, though: it's true that being strong and taking too long to express it (the "Explosive Strength Deficit" from "Easy Strength") is pretty useless in athletics. But he leaves the impression that one should train for speed-strength first and I don't think this was the intent nor the practice. In order for strength to be expressed quickly it must first be there to be expressed at all. Same goes for endurance: in order to have the strength endurance to do a task many times, one must first have the maximal strength to do it once.
Ergo - "StrongFirst". Note that it's not "StrongOnly" or "StrongThenStop".
