Cox is a goal scorer, and I believe he could score goals in the Premiership. The problem is he doesn't have the all-round game, he puts a lot of effort in and annoys people, but he is a little lightweight compared to even Morrison or Dorrans. He could probably do a job against the smaller teams, or coming off the bench when we need a goal.
I like him, and I really hop Roy can help him achieve the level he needs to get to.
