It make sense to instruct most tall rangy fighters to stay outside and maximize their God given gifts of height and reach, and in some cases it means the tall guy can stop his opponent from getting close enough to retaliate. But like all rules their are always exceptions. In close you still get to eat short hooks and uppercuts.
Oh. Mike McCallum. Watch him, he is good at boxing. Not exactly inside, but good on the mid-distance. Hits people on the disengage and while they're on the way in. Really good style, awkward as hell.
