Have you actually seen much of him, mate? I've seen a lot of people say that he's possibly our biggest talent since the golden generation, and iirc the hype around him has been big since the u19 WC, I think it was, but I've never seen him play, myself.
Like you, haven't seen him play, just followed the Shield scores and news. The hype is huge on him. There has to be doubts on him though due to the head knocks. 3 last year and another 1 this year, but this is the series to blood him against a soft Sri Lankan outfit.
