The main difference between Oli and Tammy is that Oli does not do much in a game but what he does, he does well. Tammy does a lot in a game and does some of it well. It makes Giroud the more efficient player but also more predictable. Like Tammy would not have scored Giroud's goal vs Wolves and Leeds, Giroud would not have scored Tammy's goals from yesterday (first post, first serve).
