White players are more skilful and technical (obviously there are exceptions so please don't jump on that and quote back one or two examples) so it isn't surprising that more will be more highly rated. Drogba got by mainly on brute force and determination which worked perfectly in the sort of side Mourinho had built. Even then his numbers aren't prolific enough to be considered one of the greats. He got exactly the adulation and praise he merited for making the most of his ability.
You had a point when you say black players aren't as marketable but I don't really see the linkage between this and judging a player's ability. Torres has been called shit pretty much since he turned to shit. It's calling a spade a spade.
P.S Can you really keep a straight face when saying that last line ?
