Some quick questions aboard the Marrakesh Express….

Do we (and by "we" I mean me) just want Grigor Dimitrov to be better than he actually is?

• I realize I’m in a diminishing group here, but I’m hanging onto my shares. I’m telling you, Dimitrov IS good. Which is part of the problem. He’s almost too good. This was the old Federer stumbling block: he’s blessed with so many options, he sometimes becomes paralyzed. You go to a restaurant with so many options on the menu and you need a few minutes to order, then you second-guess your choice. Go to Rubio’s Fish Tacos, for instance, and the choice is easier.
