In your opinion could an average MIDDLEWEIGHT amateur boxer beat lower weight pros like Davis or Lomachenko? amateurs train about the same amount and intensity as pros but lack talent so it would be interesting to see how much weight would be needed to make up for it...
Depends what You mean by average tier - and it also depends on style, but there's definitely a lot of very ordinary middleweight fighters that would beat great 130 pounders. Time that They'd get to gain weight properly would also matter.
