He's regressed a bit. Earlier in the season he was making runs off the ball, but the team didn't try to find him and he's either been coached not to make those runs, or realised the runs are pointless as no one is going to pass to him anyway. Technically he's not up to standard. I do feel there is a player in there somewhere, but no striker looks good in a Moyes team.
In terms of strikers alone, it seems to be a dying art of strikers trying to get in front of a man at crosses and things these days. Strikers used to be the sharpest players on the pitch, but now they're mostly big strong athletes.
