I have to go against Moore and pick The Tar Baby. I see Moore boxing well and maybe even rocking Langford around only to fall into a sudden trap and getting stopped not unlike the final Charles/Moore meeting.
tough bout both men could punch, both had experience, Archie was a bit more adaptable but 2 beast at the weight...im gonna sit this one out
This fantasy fight is a good example of the big difference between giving a fighter trouble and beating them. With Moore's turtle-defence and snaking punches he'd give Langford difficulty, but the Boston Terror's power and cast iron chin should win the day. Langford only needed one shot to scramble your senses, and Moore could be hurt. Great fight, but one boxer's going to crack, and it won't be Sam. In a trilogy, bruised n' battered, perhaps Moore takes a decision.
As much as respect Archie's great heart, and he would always do his best to get up and fight on, I feel that Sam takes one by KO somewhere in mid-late rounds. If there's a trilogy Moore will have learned his lesson and box his way to a decision in at least one.
