For the last time :
Coleman NEVER beat Yates when they competed.
Coleman himself admits that he couldn't beat Yates at his peak.
For the only time:
-You are quite guillible if you choose to place complete faith in IFBB contest placings as the arbiter, given that the IFBB and Weider have always been highly commercial enterprises with multiple agendas aside from awarding the top prize to the most deserving BB. The Olympia placings have been replete with questionable outcomes that have at times resulted in the departure of retirement of some of the best BBs in the world.
-What Coleman says is as irrelevant as the fact that Yates said same about Coleman. Or conversely, take each seriously and they cancel out, leaving you with nothing.
According to the IFBB this was the world's best build dude. When do you want to buy my bridge?
