All these comments about du Plessis in terms of the Sisa Waqa precedent are way out of line.
First, these original massive promotional comparisons of Waqa with Inglis and Folau came from Waqa's coach at Gordon Rugby Union club! That is a far cry from the head of one of the most prestigious rugby union academies in South Africa, saying that he couldn't understand why Du Plessis had left a guaranteed prestige future in South African rugby union for rugby league.
Second Peter Sullivan had only seen Waqa on videos. He has watched Du Plessis in the flesh.
Third, people who are not sure whether du Plessis is going to be that good, say of du Plessis "let's wait and see how he adapts to learning the game." Well how about applying the same standard to Waqa, eh? Waqa himself said when he was signed last December that he needed to adapt to rugby league. So why don't you blokes just give Waqa the time he needs, and the time you say du Plessis needs, before rushing to judgment on him?
