I'm curious as to why he said that Roach wasn't "equipped for that". From what I've seen, Morello was a pretty blunt guy. Was that a dig at Roach or did he really lack the flashy Big Band era chops like Buddy and Louie? I really haven't listened to enough or Roach's stuff but from what I have seen he was really more of a contemplative Bop player.
I think he's just saying that Max Roach didn't have the flash that Buddy had, especially the Single Stroke Roll... that was Buddy's signature, and he could play it super fast. Max Roach was more of a musical drummer, so he probably didn't sit around getting his roll to be blisteringly fast. That's not to say that he wasn't fast, but he just probably wasn't a flashy as Buddy.
