Morkel has been adequate... I guess we have been spoilt by genuine match winners like Dale and Verne.
I think I expect a lot more from Morkel, but you are right, he has been better this year, but also due to him being mostly disappointing previously in test cricket... Largely because he is extremely highly rated by his team mates and coaching staff.
The problem is he open up the door but he didn't batter it down. 3 wicket is nice and all but Steyn used to battered the door down once got a sniff. He wouldn't settle for 3 he would have taken the killing blow.
Felt he should have done more on that final morning of the last test. There was an opportunity after we rattled england early. Convinced if we had steyn there he would have landed the killing blow instead of just rattling england.
I think it has to do with what a bowler like Morkel is going to give you vs what people expect from him.
I remember in the 2014 series, everyone, perhaps even the SA team to an extent were trying to pit Morkel against Johnson.
Morkel bowled a pretty tough spell against Australia in the third test, without much to show for it whereas Johnson of course destroyed South Africa in that series.
Now here's the thing, Morkel, just because he is tall and quick is not Johnson, and he is not the bowler who will take 7 for 30 and win you the game in a session.
He is not Steyn, or Johnson or Akhtar or any of those bowlers that he is often categorised with. He just does not have a wide range of skills or wicket taking deliveries. Wahab Riaz is a bit similar to him in that regard, they bowl with pace and bounce, manage to create pressure but they only have a limited number of wicket taking options, which is why neither have many 5 fers nor do they run through sides like they are expected to. I used to be critical of Morkel too but having watched the India-SA series and having seen Wahab do this pretty much all year, I observed how similar both of them are, especially in their limited wicket taking options. despite creating the pressure.
Morkel is going to give you a top notch spell of sustained pressure, built upon consistent quick bowling, troubling the batsman repeatedly. If the team is lucky and it's their day, a few wickets will fall, if not, tough luck.
But that's what you're going to get from Morkel which is why he has formed such a successful pair with Steyn because his sustained pressure helps Steyn's extensive repertoire.
Is he going to 'replace' Steyn and give you 6 for 8? No.
You need to find another bowler for that.
I thought he bowled as good as he ever has in the last few games, but the coach has expressed some worry about his workload. One has to factor in exhaustion and fatigue in the last 2 tests as well.
