did u see the match, Sean? It is not about competition for wickets.. You could have had a bowling line up of Ambrose, McGrath, Warne and Murali and Murali would have still got those 7 wickets today. He got them all with very good balls, except for Sachin which wasn't a great shot... It had nothing to do with how good or how bad the bowler at the other end was.
Edit: And there was a BALL OF THIS CENTURY involved there too, the one with which he got Dhoni. He bowled around the stumps, from wide of the crease, it was a doosra, it pitched quite a distance outside leg stump and turned and hit off stump. It would have been called an awesome delivery if it had been bowled by a leg spinner, but this was from an OFF SPINNER. I personally felt honoured to have watched that ball live, even though it was on live TV.
