Roy Keane was a bully in the same way Jordan could be, but had about a tenth of the natural talent.
Don't get me wrong, Roy Keane was actually underrated by some, who thought he was just a thug who went around kicking and intimidating people. He was one of the best passers of a ball in his prime, and many of them were dangerous passes forward. He could also run with the ball and got around the midfield. But there is no comparison to Jordan, who had all that fight plus all the talent and finesse.
