Louis was the FAR FAR greater fighter. Not close in any way. Louis prime weight was 202 this was as per Louis himself. Foreman was 217 when he fought Frazier in 73 and many think this was his best overall performance. So it's a 15 pound or so difference in weight. Inconsequential.
I agree. Foreman was a naturally big dude. He looked great even over 230 Lbs. and with his frame would no look undersized vs. any fighter.
