Joe Louis and Thomas Hearns are great calls, but the most powerful single right cross in my lifetime - Frank Bruno..

Michael spinks had a helluva right cross but i'll go with arguello on this. hardest heavyweight right cross? I gotta go with wolfgram. nah, shavers right cross was the big bomb but I concurthat it wasn't quite so straight. u know who threw a sneaky right lead that had devastatin effect? witherspoon. no not chazz. tim witherspoon
