Zardes has 7 goals and 9 primary assists across 33 matches worth of minutes which is outstanding when also factoring his Copa record. That's a bit more than an ignorant/patronizing 'hardworking' appellation. He has an excellent record at forward as well as at wide midfield. His record at forward in MLS is also outstanding. Individual coaches have their reasons for moving players around; see, for example, Adams. Under Berhalter, Zardes has a goal and primary assist in 4 matches at forward. He is scoring/assisting at his normally excellent historical rate.
