Not head to head. For one thing Tua was an animal in the gym not the saloon. Elsewise, Tua actually had things like balance and a guard and packed power in both hands. He didn't need to throw his left from the next county to get power on it... They are nothing alike.
He also swam with dolphins. Tua dealt with sharks. He just didn't deal with them as well as his advocates make out.
The problem here is that Galento clobbered most of the dolphins, and Tua got eaten by the sharks! The biggest dolphin that Galento beat, probably batters all the small sharks that Tua beat!
What does going 38-3 86 percent KO rate have anything to do with dreaming of beating Louis? Does Tua go 66-3 with a 75 percent KO rate against Louis opposition? Would hope you are being honest here and say absolutely not.
Who said anything about early on? Galento was still losing to unimpressive unranked guys 6,7,8,9 years into his career...
