No, not really.
I'll admit that he was ineffective early in the season. In the first 4 games, he only won 1 of 10 headers. I think this is another case in which a player gets off to a rough start, earns a reputation, and can't get rid of it no matter what he does. Since the West Ham game, Zamora has won more headers than he's lost. It might not sound like much, but that's hard to do for a striker. To put things into perspective, Brian McBride won 34% of his headers last season. Clint Dempsey won about 36%, and Shefki Kuqi 42%. Zamora is sitting at 43% so far, despite the slow start.
