How are they particularly bland though? Djokovic produced an absolute classic today and is exciting to watch. I'll admit that Murray isn't the most exciting to watch but people exaggerate how boring he is by acting as if he's still the player he was back in 2009/2010 when he was a lot more defensive than he is now. Tennis is in a great era at the moment and people still feel the need to constantly complain. Their match at the US Open last year was excellent and there's nothing to suggest that if Murray wins their final on Sunday won't be a very good match.
I'm not talking about the quality of the Tennis. Djokovic is obviously the best in the world and deservedly so. I'm talking about both his and Murray's personalities. They seem utterly generic and struggle to stir the imagination. Federer has occupied that role for the past decade and the likes of Rafa and Del Potro have been excellent foils. The sport needs more outgoing personalities in the Connors, McEnroe, Becker, Ivanesevic, Aggasi mold.
