Boxers who you think would NOT have been so great if not for their size

[Beanz]

Vitali.. Vitali uses his height as a defensive mechanism as he leans back to avoid punches but without his height and reach, this would have been impossible for him. So yea, I pick Vitali as one of the guy who wouldnt have been what he is without his size..

Wlad on the other hand. I think he would have done well without his size due to his intelligence and boxing skills...

Vitali's boxing style was born out of kickboxing...granted his height might give him the advantage to lean out of the way of punches better than most, but honestly he just sees punches coming so well he's hard to hit in general.

That is true and you have to remember at 79 inches Vitalis reach is shorter than most other Heavys, including guys like Ali who people just assume would not be able to compete today. When guys are trying to kick you in the head you develop good defences pretty quickly and though often that does not translate to making you a natural boxer there are exceptions and ways of building on that fighting foundation. At the other end of the Scale tiny Scott Quigg has a background in martial arts and it has definitely helped hone his reflexes, but he has built on that with great boxing specific footwork and punch picking skills. You play to your strengths but if you want to be great you can not let them define you. You have to become well rounded and bring your deficiencies up a level. Being huge but slow and clumsy is not gonna help just as being small quick but fundamentally unbalanced and easy to outwork will not win you belts.
