Debatable.
Mate watch him closely next chance you get. He rarely is close to catching attacking bombs like the one Naden scored off 5 times out of 10 Waqa knocks that on, he is more effective taping them back but he still fluffs that sometimes by mistiming his jump.
I like Waqa I don’t want him to leave but of all his talent and abilities his aerial threat is one of the last arguments I’d be making as a reason to keep him. His speed, size and footwork are his brilliant attacking attributes and his defence was awesome last season.
