There's no doubt that Siddle puts in the effort....but he can't take enough wickets and that is what wins games...Hilfenhaus is even worse at getting wickets. I know these guys are trying their hearts out but the results are not good enough. That game should have been won easily. If you are trying really hard at your job but getting bad results....guess what you get fired. As soon as there are good fit replacements available for them they need to be dropped.
I am sorry but I have to disagree with some of points; I agree that our bowlers need to take more wickets but we have to put the game into context. All SA wanted to do for the last 4 sessions was save the game do they played such a defensive game which on a very flat and mostly true wicket really worked in their favour. Let's not forget our best quick was out of action also and the amount if times Siddle beat the bat was astonishing. SA apparently have the best fast bowling attack in the world but aldo struggled to bowl Aust out. If we drop Hilfy we lose our only genuine swing bowler and if we drop Siddle we loseour best stump to stump bowler who is able to easily tie one end up in the high 130's for long spells. Really tough call to drop either one but if we had to I would say Hilfy first
