Re: Do you think Robinson was ever the same after he accidently killed Doyle?
No doubt it haunted him forever but I don't think its easy to say how it affected his ring style. I don't think the effect was as visible as was the case for guys like Brian Mitchell, Emile Griffith, and Chris Eubank, who all held back in the future when they had opponents hurt.
Clearly Robinson was still a devastating finisher afterward, perhaps the best finisher ever. Maybe it lessened his already waning zeal for combate, but not substantially.
