You must have a short memory of Siddle yes? How do you suspect BF dubbed him "right arm poo"? Though this looks like its in the past, and he has learnt to become a quality bowler. We all love Sids and the attitude he brings to the team.We're talking an ability to take wickets while staying fit and not getting carted all over the joint.
Even still, Lee is still better as it stands imo, but that opinion changes from person to person so it's up in the air.
