Philander would be typically be opening the bowling, not bowling change. If it is seam friendly he will typically be better than either of the others, whether or not it swings. If there is a lot of swing, anderson gets the new ball. Steyn swings it enough plus has the pace to be fine as a change bowler ala England 2012ish.Coronis just lists the suggested players off the top of his head, and sometimes forgets some. Dale Steyn wasn't listed in the opening bowlers section before but obviously won anyway. You're absolutely free to vote for Johnson if you like.
Philander's been the next best / most influential bowler of the decade but I don't really love the idea of him bowling at first change given how reliant he is on seam movement. Cummins has been gun but has been playing for less than three years (excluding his dayboo), so I kind of don't hate the idea of Johnson myself. Rabada and Morkel are the other two I'm considering. I'll come back to it later.
He had a few awesome series pre-2010 Too but they don’t count for this, obvs.Peak Johnson is probably the bowler you want to round out any attack. But he was only peak Johnson for about 4 series in a long career. Not good enough. Plus he only played about half the decade. About the same as Rabada, who has only had a couple of series that he wasnt great in. Cummins and Bumrah if you want to get progressively more silly on the minimum time frames.
Morkel isnt a bad shout. He balances the attack well, and had a good, long decade. He was utter trash in the 2000s, but improved a lot.
