Which physical advantage is the best?

[B-Bomber]

pretty sure waht the poster meant was
weight "advantage" like james toney would have on fight night.
note the quotes^

In that case it has to be reach , since height without reach is not going to help much.

Nonetheless , I find reach to be very much overrated nowadays. Just because the HW division is so unwatchable and Wlad can keep everybody at the end of his jab, it doesn't mean that reach is this huge advantage.

If I'm not mistaken Wach had a reach advantage over Wlad, no?.

It is not in the given options, in my opinion though, excluding weight, speed of hand and foot is more important than mere reach. Somebody much faster can easily trick a rangy fighter and get into trading range and then out. Think of Pacquaio for instance.

height because being in the lower weights you'll never see the money you want

or is that weight?

Speed.
