Jay was actually pretty strong. I seem to remember him inclining 405 for a few. Cormier could incline 405 for at least 12 and Dennis James could press a shitload, even if he didn't touch his chest at the bottom of every rep. Even Dorian was an outstanding BB incline presser before some of his injuries. I know a guy from Temple Gym who swears on his kids that he saw Dorian incline 455 for 7 very strict reps sometime in early '93.
Ronnie was very strong overall but there are a number of pros who could equal or beat him on some lifts. If memory serves, he and Levrone had a bench-off not long after Ronnie won his first Mr. O or two. Ronnie did 500 for a triple whilst Kevin got it for 6.
Ronnie really shined in DB presses. I think most pros were too chickenshit to even attempt 200's for flat or incline DB presses, but Ronnie just saw it as another day on the job. And there really ARE few pros who could equal or beat him on the DB presses he did in "The Unbelievable." His prowess with the DBs leads me to believe he could handle much more than he did with a BB but, for some reason or another, never quite realized his pressing potential, at least in a powerlifting sense.
