If I may meander slightly back then, if they are the same height, I'll say that watching Alexander from the stand it was obvious and is testament to Davis' quality that he didn't seem to get caught out with the same disadvantage.
I thought Alexander was more dominant in his box and far better at coming for crosses than Davis. I don't ever really remember him being caught out certainly no more than Davis!!!
SKD would be a cracking addition - not only very capable in the championship but also a big character which is what you guys need at the moment
