yeah, the guys in the older generation DID have personality. So many of the guys today are just boring. There's no flair, no personality. I miss the characters of a few decades ago. One reason why tennis ratings largely suck is the personalities playing today have all the spice and appeal of day-old oatmeal. Boring.
but re Djokovic, yes, he DOES have the killer instinct. At least this year. What he's done this year has been absolutely remarkable. Dude has just stepped on people's throats and not stepped off until they were cold and dead.
