Not that i'm a deadlift master or anything but that was a solid article although as Steve said nothing really revelationary.
Allen, I'd say that rRck is talking about deep explosive swings. Since he is involved with the Diesel guys that may even involve swings with a band for extra nastiness.
As far as speed goes i've found that I if i do lots of heavy, explosive pulls then my deadlift increases slowly. It doesn;t rocket up like it might on a dedicated DL plan but i'm finding that if i work up to say heavy triples of 140kg in the Clean pull (with straps) then 210kg DL is no problem even without doing ANY max or near max DL for ages.
