Assist just are, do not reflect true ability and contribution of a player, Ozil is the classic point in case.
I've had a thing about corners and their effectiveness (lack of) for years, crossing is just an extension of that. It bugs the fuck out of me that people love crosses so much, when in fact they are such poor way to score a goal from, people think the exact opposite. Trippier gets it in the neck from me because this is all he can do. But because people think crosses are great many are saying Trips is better than Walker as a result. All I see is an attack break down almost all of the time when Tripps crosses a ball into the box. What a waste, if only he had the ability to take on a player, turn a defender, slip in a cheeky ball to whoever instead of whipping in a ball that misses everyone.
