Weak, because he would probably gallop away from the other big horses with good shoes on. Until those horses were ancient, then he would gallop back.
See cause the shoes ON is def. an advantage, and had he done his work with the shoes OFF it would have been a much greater feat, in the eyes of many.
It depends on whether he'd duck Secretariat, who would be coming off a 9th round TKO victory over a prime Mike Tyson.
Consider this, sir. What IF the other big horses did NOT have shoes on? What then? Joe would have an advatage for sure there, so we can not say for sure. :think What say you Dinamita?
