Tua's problems amongst other things is age. David aint no spring chicken. and short heavyweights don't age as well as the taller fighters, its very important that he works on that weight , or top opponents will just pot shot and run like hell and he wont be able to catch them . He’s got to be lighter , so he can close that distance get those hands moving and get that magic in there. Tua needs to find his way to 227lbs, even if he has to buy a map !
