100 percent correct, its a collective effort. High level cricket relies upon having the skill sets to execute plans, and that's the problem I have with Starc. Part of that is sustained pressure, and he releases it too often by bowling junk. Sure, he gets wickets with Jaffas and that's a legitimate approach to taking wickets, but he seemingly doesn't worry about the other rubbish and that hurts the collective bowling effort. He is also deadly when conditions suit (eg the night test Adelaide) but so often on flat decks he's old rope. I thought he was a highlights package bowler in the ashes (images of him getting carted) and was staggered when he received a gong. In the two most recent home series vs. India he shouldn't have played the last games, he was below par and we lost both.
Starc is bowling like crap - and has for some time. I'd be playing Morris next test because Starc's not contributing enough. Seriously, Paddy can't bowl him versus the tail, he's too expensive.
