If you give me the choice of great spin options and OK fast bowlers, vs. great fast bowlers and a OK spin bowlers, the latter team will be more successful virtually everywhere. Obviously, they do different things, but in almost any scenario, a bad pace attack will hurt you a lot more than a bad spin attack.
A great spinner is a great thing to have in the side, but if I have top quality quicks (something like Holding, Garner, Roberts, Marshall), I'd much rather play all four of them then any three of them and a Murali or a Warne. That's all I'm saying.
Obviously, if a spinner is one of your four best bowlers, or if the pitch is going to be turning square, you play a spinner. That's fine. But overall, in terms of the impact on a win, I'll take a top quality pace bowler over a top quality spin bowler.
KaZoh0lic said that Warne/Murali are on the same league as someone like Malcolm Marshall...to me its not even close, and I bet I'd win a lot more games with Marshall than Warne/Murali.
