He might not have Parker's speed but he's still very ing fast. Not many folks have had Tony's speed, tbh. He was one of the fastest players ever. Besides, why are you limiting physical tools to just speed? Just because it is the one physical attribute that Parker has over Murray?
And lol at the thought of Murray not having any skill.

if he doesn't have skill then what is left for a guy like Danny Green?
Many folks seem to forget what a young Tony was. He was kinda like a young Murray. A kid with potential but extremely raw. Or do you forget that he couldn't shoot for ? That on fastbreaks he would mindlessly take on three defenders all by himself and, inevitably, turn the ball over? That he had tunel vision? It's easy now, after all that Parker has done, to laugh at the idea of comparing Murray to Tony. But I don't forget all the flaws that a young Tony had, tbh.
