One last point. I've noticed one or two posters commenting on Crouch's two headed goals in the last two games and alluding to the theory that he has been doing stregthening exercises. I don't buy into this opinion at all. For me the oproblem with Crouch as a header has always been that he fills the spaces too early. He tends to get into the heading zone a fraction of a second early which means he has to head either from a standing jump, or worse from a slightly backwrds jump. It's probably a legacy of his lower league career whereby the simple fact that he was tall meant he could be successfull, despite poor technique.
Sorry to cut this piece of a good post Bigmick, but if I quoted all of it the pages would have a few posts only.
Not that I think that point about the timing is wrong, but I think the body factor is also involved, good headers like John Aldridge's required a very specific body movement that quite simply you cannot get with the height of Crouch.
Zigic a player that is about an inch taller than crouch has the same problem. Even if you strenghten your muscles to jump more it's required a lot of coordination, there are computer programs for proffessionals that I've seen, that study all the movements that a player do and coordination is very important.
This piece of software have been used by RS, Barcelona and other teams to spot mistakes in the runs of players before kicking the ball and thus being able to correct them.
I just wanted to add this point about the body, IMHO timing counts but body aswell, and good headers require a lot of things to be well done.
