Was Sonny Liston's jab really that powerfull or is it more of a myth?

In close to 2/3rds of his fights he was as big or bigger though. Proving that Tyson was a good size for his era. There have not been to many great heavyweights that have given up weight consistantly.

I think Holyfield may be the heavyweight that was the smallest during his time which says something about Holyfield's ability. There have been more great heavyweights that are consistantly bigger then consistantly smaller. Even Joe Frazier was only out weighed about 10 times.
