Ljubo has beaten all the current top 10 players, most in last year and half, so he deserves to be there, more than "i play 50 tounys a year Davydenko"
first of all i agree with you, he earned his way there but im thinking that without his serve he would have no chance against a player like canas, so imo canas has a good chance to get to top 20...
its not like all his "50" "tournys" count, but yes, it is a better chance to gather points that way, but then again some players dont have the stamina to play that much tennis per year, so give some credit for the russian boldie too..
i hope you get my point, its past midnight here and my posts might be a little "blurry"! thank you for your understanding
