When he had that two-year stretch he was one of the four best in the world and kept finding Federer on hardcourts. He's cut in half by being weak on the other two surfaces but he's still a good hard court player.

I agree with that. I don't think he'd be high on any 'slam results' list, though. Despite good results on hard courts, I think he has a history of underperforming at slams.
