Theres some great fighters have turned it round, recently Hagler, Wright, Dela Hoya come to mind. Hagler tried to switcth against Mugabi and Leonard but it didnt work its hard to do it going forward because of eyesight. going forward switching gives the brain througth eyesight the wrong messages for distance, so someone throwing a mixture of straight shots and hooks at someone using that technique youll have success. Going backwards that way is a good way of confusing and stopping the other guy from fighting which is a plus. I think the fight which demonstraes this best was Barerra v Naz, Barrera didnt go looking for Naz He made Naz come to him took a half step back and met him, a very good game plan. You take your pick.
