Rose-coloured glasses or not, comparing Naitanui to Scully or Trengove is amazing. Both demons possess wonderful football brains and execute (almost always) their skills efficiently, whereas Naitanui (as some have said) is patchy with disposal, decision making and many other facets of his game. Being a brilliant athlete won't necessarily cut it for a decade at this level. He will have to improve his know-how, execution by both foot and hand, and keep himself involved in the game for longer periods of time.
By comparison, Watts has all the skills, the decision making and will have the midfield at his disposal to forge an exciting career at the MFC. Do I regret we took Jack instead of Nic? I'd take Jack ten times out of ten.
