Mono, and its severity, is quite hard to generalize. It ended Ancic's career but has spared Roddick and Fed. It remains to be seen if Soderling can recover and return to top 10 status. One thing is certain...as a new father (baby girl born October 12), his perspective will vastly change. Even if the body heals, his interest and focus may be compromised by this new role.
Good luck, no matter what you choose, Big Swede!
It's good to be G.O.A.T.; 4+ years of the TTW wars!
