Why Manny can't be compared to the likes of Armstrong or Langford.

Manny and Roach want Cotto to make 145, why not just fight at 147. henry armstrong and sam langford would never moan and ask for catchweights bouts, hank and langford would often give away lots of weight, but didnt care. when napoles fought huge middlweight carlos monzon he didnt make monzon come in at catch weight, when robinson fought jake lamotta, robinson didnt ask for a catch weight and gave away 16 pound. makes me laugh how, how freddie and manny are moaning for cotto to get down to 145, if they want to fight best cotto,fight him at 147, by making him get down to 145 he isn't fighting the best miguel cotto, langford or armstrong would never have done this! i feel if the fight is made at 147, cotto would beat him. manny is a great fighter. but is letting me down with these daft catchweight fights, the likes of armstrong and langford would be turning in there grave's.
