I reckon McGraths just about young enough to be considered modern day, although take your point that he's a different generation. I'd have to say there's a bit more than a slight difference between the likes of broad and the players in that list.
In terms of total wickets, it's a hell of an achievement but I'd put a lot down to his durability as well as his talent. It's very commendable how he's kept himself in shape and says a lot about his natural strength and a good fitness regime. But by the same token, I don't see dale steyn as a lesser bowler because the injuries kept him to 400 odd.
I think Broad summed himself up better than I ever could:
“I think ultimately how I’ve played my sport is, I’d never want anyone in the crowd or watching at home to think he’s not giving absolute everything, he’s not putting his heart and soul into it,” Broad said. “I know I’m not the most skilful player, I know that I need every inch of my competitive spirit and my drive and my effort to get anything out of my ability. And I would say every day I’ve put on a Nottinghamshire shirt and an England shirt I’ve given my heart and soul. I can’t think there’d be too many cricket fans out there that would think I’ve slacked off for a moment.”
