He's just very inconsistent. Good start at United in his first run, then mistakes crept in and he was poor for quite a while. His involvements in the last third of the season were pretty good, but then he still has 1 or 2 performances where he has big lapses defensively. And when hes playing poorly defensively, or making a bunch of mistakes defensively he isnt good enough on the ball to make up for it with attacking contributions. He's still young and hopefully after his first season he becomes a more solid and dependable backup, but there is cause to be concerned that he wont be just yet and that would leave us short.
He's fairly quick, agile, can pick a decent pass when he's feeling confident and playing well. And he likes to get tight and make tackles, like a mini AWB at times. But if he makes a mistake and loses the ball or fails to track his man back and it leads to a goal he crumbles from a solid performance to a poor one.
