I think we're all saying the same thing...drogba lumbered and picked up speed, but not very quickly--a very powerful runner nonetheless. Though when he hit his speed he was moving pretty quickly, without a doubt. He had a great stride and great balance, though didnt have the quickest first 3 steps. Lukaku is a freak of nature, whereas his speed is, at worst, up there with Drogba's, he explodes out of the blocks like a sprinter. Phenomenal stride length and frequency, he's a specimen. One must consider that "game speed" is a function of timing (when to run), stride length/frequency and balance (body position relative to opponents)...lukaku possesses a rare combination for his size. Too big to be knocked off the ball by a smaller defender and too fast to be held back or caught up to (ask Carragher how that went). Just an observation, feel free to criticize.
