Tremlett at his best is better than Broad, but I would imagine (again, rightly or wrongly) that given that Tremlett is not guaranteed to be better than Broad with the ball, Broad is pretty much guaranteed to be significantly better than Tremlett with the bat. So, given two bowlers of a similar type, they've opted for the incumbent, who also happens to be the better bat.Maybe. So is Flintoff, of course.
Goes without mentioning that Flintoff and Tremlett both > Broad.
Pattinson chosen over Tremlett as a more direct replacement like-for-like for Sidebottom. If the last test taught people anything, it should be that a bowling attack needs to have slightly more than one dimension.
