People get caught up in stuff like the deadlift because you build up to what seem like big numbers. But the fact is, it's not very impressive. Most guys can get there. And it's not very useful, athletically speaking.
I think Rippetoe's original schtick was built around bulking kids up for certain positions on high school football teams. Having an extra 20# to throw around at age 17 is going to really help a lineman. I'm a bit skeptical about the wider reverence the Rippetoe approach gets these days.
