I have read Rippetoe before, and usually found myself disagreeing with him....primarily because I think that the 1RM is overly worshipped, and that strength without endurance is pointless and non-functional. I have played enough sports to see a lot of "weight-room beast, on the field least", or big monstrous guys that look like they would be good players, only to see them wear down into little girls almost immediately.
But that article was a little different. Strength has a place, a REALLY big place in any athlete. I think he puts it a little more in its rightful spot here.
Because I have also seen plenty more of the opposite....guys that are supposed to be "naturals", are quick and can run all day, but are like hitting a spaghetti noodle. I like the reverse being said for me, a comment made by a guy on another team after a game that made all my training pay off in one sentence: "Dude. Hitting you was like trying to tackle a fire-hydrant."
Strength matters, a lot....it's just that it's 75%, not 95%
"They now look to a single and splendid government of an aristocracy, founded on banking institutions, and moneyed incorporations under the guise and cloak of their favored branches of manufactures, commerce and navigation, riding and ruling over the plundered ploughman and beggared yeomanry." - Thomas Jefferson, 1826
