Jimmy Anderson was a raw talent though, not an experienced bowler like Sidebottom. Anderson also offered more than swing and swing alone. He's got good pace, and is a handy back of a length bowler. Anderson of 3-4 years ago was still better than Sidebottom of the last 6 months for mine. I don't agree that left handedness is a massive asset when it's not swinging. I think the key to being effective as a left-armer is swing, and when it's not swinging there's no massive benefit to bowling left arm. I'd much rather have someone like Onions, Flintoff, Bresnan and even Harmison ahead of Sidey tbh.
You must really love Anderson, or really despise Sidebottom but there is no waaaaayyy Anderson 3-4 years ago was better then Sidebottom 6-12 months ago. I'm really hoping Sidebottom plays in the Ashes, he would be a real handful for them unlike Broad and Onions.
