ronnie also had straps. regardless of his "tiring out", the point is that johnnie has done heavier weights than ronnie has. that's just the simple facts. johnnie's best deadlift as far as i know is 814 weighing 230-ish and it was done three and a half weeks before the 2001 nationals. his best squat is around 830. these were competition lifts, while ronnie's pair of 800x2 lifts were done in the gym and obviously neither would have gotten white lights (his pull due to straps, his squat due to depth).
now, ronnie's a better bencher, and he's also stronger on some of the more bodybuilding lifts like rows.
