Simple. Can a wrestler that is 5'9" make it without having to be a gymnast in the ring? How big do you think one would have to weigh before they are of respectable size when 5'9"? Would hate to be a glorified jobber like jamie noble was. Should one even try breaking in to the business?
EDIT: Bad of me to mention jamie noble due to limited wwe viewings of him, i am the same size as him right now which is why i used the example but it was wrong of me
Just search pro wrestlers by height and you'll know. And to answer your question, yes they can.
