Ali debuted in the pro's at over 190lbs and never weighed under 190lbs. The last time Ali weighed under 175lbs was as a skinny 18 year old at the Olympics I suspect the Patterson who most felt deserved the decision over a borderline ATG LHW, Joey Maxim, and who beat Yvon Durelle, would have beaten an 18 year old Ali yet to make his pro debut.
