No, I cannot think of any of our players who have improved dramatically in the air but I get annoyed when someone who is tall but cannot time his headers right. We had players who arent tall but were excellent in winning the balls in the air. My dad tells me a lot about Doc Pace and Joe Shaw, I remember John Tudor and Ian Bryson were good at attacking crosses despite not being tall and at present we have Terry Kennedy who is not tall but good in the air. Lou Macari was very good in the air for Man U despite being only 5 foot 6. I remember reading in Alan Birchenall's autobiography that Dave Sexton told him to be as late as possible when making your leap to head the ball and Alan said that helped him a lot.
In the last 45 years I have followed the Blades there are two of our players who were stronger in the air than Brian Deane, they were Gareth Taylor and Paul McGrath
