Agreed on Staines. He seems to be a favourite on the forum and has some positives as a player, but just don't seem him as an NRL standard winger.
His kick returns are poor and often gets forced back to his own line. His post contact metres would have to be the worst of any winger in the comp. Tupou cops a lot on this forum (fair enough for his errors) but he is much less of a liability considering he actually makes good metres early in the set and gives us a good foundation, is a threat in the air and can finish just as well as Staines
I would replace Staines with Naden when hes back fit. Naden is just as quick, if not quicker than Staines, has more skill, is a better ball runner, makes more metres, is better starting off sets and is an aerial threat.
Overall we need to improve the wing position maybe more than any other, but based on what we have right now our best options at wing are Tupou and Naden (if we are not playing Naden at centre).
