TT also has alot of improvement to go. I believe he had more errors than any other FB last year.
He led the league in errors overall, not just fullbacks.
But he was also top 5 in try assists, linebreaks and run metres - so plenty of good to outweigh the bad.
I suspect a few of his errors were forced passes in attacking situations which he will learn from, and in fairness to him fullbacks are put into the most error sensitive situations (top 5 error makers were all back 3 players)
