Harrison has been wasteful at times, no question. At the same time he has contributed a lot of key moments, a goal and 4 assists in the equivalent of 7 full league games is decent for a wide man, and he defends diligently and intelligently, in a way Dyche wants his wide players to. In short, he's more than justified his place so far after coming back from a serious injury. He helps to give the team the balance it is displaying. In a perfect world he shows a bit more quality on the ball more consistently, but if he did there's every chance he would be plying his trade higher up the league.
