You think he will learn? He was going to play in Los Cabos in yet another 250 event, during the Olympic Games. Davydenko pales in comparison to Thiem, who will play in all the 250 events if time allows it. Luckily some are played at the same time....
You've got to hope so. I guess they both planned their schedule based on last year... both have exceeded expectations and played a lot of tennis. Maybe they'll continue rolling with it for the remainder of the year but you'd expect a re-appraisal for next year.
