I think we may have discovered the most overrated shot of all time
Roddick and Querrey are both taller as well but Federer still has a better serve. Karlovic is taller and has more pace in his serve, but it's still arguable that Federer still has the better serve. So, what's your point?
Seriously, how can anyone believe that Federer's serve is better than Roddick's or Querrey's, let alone Karlovic's? Because he holds real easy? Ever realized how his groundgame is miles ahead of these guys?
