I'm undecided as well...Just an opinion but Valdez, problably hit harder than Robinson. Power with valdez, timing and speed with SRR...In the comparison of the two.
I'm pretty sure that LaMotta would lose. Given the trouble he had making 160, you'd probably have to remove a limb to get him to 154.
Valdez by the slimmest of margins. LaMotta is always a tough customer, but Rocky would have the edge in power and would land the more damaging shots overall. Still a great bout, though.
