Yes Jim Fryatt the best header of a football I have ever seen.(that includes all the top strikers before and after him). Not just power either because in front of goal and whatever distance he always headed down onto the line. For a keeper that's just where he doesn't want it. The only player that came close was Dennis Law who like Fryatt had a prodigious leap with power and precision. Bert Lister was quite short for a striker and his headed goals were usually diving. GN9 is a good header(similar stature to Fryatt) but I would put him a good bit behind.
