Keep hitting it as hard as you can Davy, even if that gets you out of position. Nobody of the Federer era had/has a tennis brain apart from Roger. We all know what happened when a few young guys came on tour that didn't have the tennis IQ of a squirrel
So Davy should be able to change? Wasnt it Rafa who said "I'm not that good to be able to reprogram my style, I only have one, it's virtually impossible to change it,''
