Who comes up with these comparisons ? Tito Trinidad never lost a fight as a welterweight... He moved up to the middleweights to lose to Bernard Hopkins then to Winkey Wright (not sure I spelled correctly ) who was fighting as Jr. Middleweight and Middleweight... Trinidad was a really good boxer with power on both hands.... Crawford who ? Crawford, Spence, Teofimo, Lomachenko with less than 30 professional fights.. Give them time, please.
Not only size but jab moment chin and power, Tito won't respect his power and will just go for the kill.
The last welter Id pick against Trinidad is a prime Hoya. Spence, Crawford, Cotto, Mayweather, Pac, Hatton.... he beats them all imo. I might be over rating him but to me he was just a beast, I dont think any welter since Hoya has had the required combination of dimensions, talent, durability and skill, to beat him.
