I wonder what his career would have been like if he had been more conservative and concentrated more on his jab and threw less power punches?! I'm especially thinking of Hagler and Barkley.
Would've beat Barkley, maybe, but Hagler and Leonard would have always forced the fight and then he would always have to fight to stop the tide. If he had the discipline and composure to stick to jab and move, he likely ends up being seen as a genuine rival to SRR's WW greatness H2H. Part of what made Tommy great was also one of his biggest vulnerabilities.
Solid choice. I was going to say Whitaker, for its great accuracy and versatility but this is 'death' by 1000 jabs, so Tommy is probably a better choice.
