As a former boxer, I believe that there are a few body types that are well suited for boxing (and different types fit different styles) the same way in soccer you want different types/skills for a goalkeeper and a striker.

I started doing kickboxing but my leg speed/flexibility was a very limiting factor and I sucked at it. I would be floored by people that were training for half the time I was, but my hand and upper body agility was suited very well for a 'in-fighter' kind of style in boxing. I changed and was able to very quickly start having boxing matches and winning them.

I truly believe different sports require different body types (fast/slow, tall/short, etc etc) and sometimes is just the problem of finding the right sport for you to be proficient in. (I was a very good goal keeper when I was a teenager, top in the region, but when the other kids started to have their growth spurts and I didn't, my 'skill' compared with the other kids started to decline.)
