It's interesting everyone writing off Mitchell who is a year younger than Sione. I'm pretty confident Sione will never score a 60 metre solo try beating 5 defenders in the process. For that matter someone let me know when Robson does that too. I have a theory on Sione that he has been doing senior-style training since he was very young, because his older brothers were already in the system and he seems like a very driven type of character. Meanwhile other 15 year olds were chasing girls and smoking behind the art block. Might explain why he was a lot better than most in the junior sides (Solomone Kata aside), but hasn't got much better since.
