I have read the stories of Roger endowment on several threads, here and others. Some have Him as above average. In the 6+ range. I personally believe the 'small' comments are just mean spirited due to His Tennis greatness.
Average combined with His handsome face, great fit body and personality works for me! What matters most is how He works it. If He can work it like He does on court, I'll take His average anytime........ANY DAY!!!
