Dirk Gently It just means they have to develop other skills to compensate.
Nicky Shorey was pretty small, but he had learned to jump and time his jump to perfection, so he was easily as good in the air as a lot of other taller players.
Compare and contract with Peter Crouch, who'd always had a height advantage and so never really had to learn to time his jump - if you look at him when he's going for headers where he has to jump, the way he jumps and his accuracy at getting the ball is pretty rubbish.
I’m not convinced that picking someone with the PL record for scoring headers is a good comparison
