Yes Tui caught that crucial 40/20 in-goal which led to the winning FG, and yes he's made a try-saving tackle, but are we really settling for that and defending him for those small moments? Those moments aren't going to be apparent in every single game, we need a well-positioned, hard running kick-return from our FB that can link with the OB's and sniff around the ruck. That's what drives throughout the 80-minutes, setting up the 6 tackles in-turn, leading to winning games. A small moment securing 2 points or 1 point over the opposition is not good enough. When push comes to shove, having the worst +/- in the top-8 is going to kill us.
