Two ways to see this... Firstly, in 1915, Ketchell long in the tooth (we're assuming he didn't get shot), Darcy young gun. Who wins? Secondly, prime for prime, assuming Darcy even reached such a status.
Interesting one... In 1915, Darcy - he was a clean liver with a granite chin, and Ketchel would probably have been as you said, too long in the tooth. Prime 4 Prime, you can't look past Ketchel given the quality of opposition faced and the many unanswered questions surrounding Darcy.
Darcy was still in his teens, for the first 10 months of 1915 anyway. He'd have been far too physical for Ketchel, even at this time. I dont see Ketchel lasting 20 rounds with Darcy at this stage at all. Darcy all the way.
I dont know?? ..Im fascinated by OLD TYMME boxing!! Darcy Seamus where do you see Darcy if he were going today???:roll:
