I agree with this in large part but, and perhaps this is just me, whenever I've been on the end of a hiding from someone teeing off or belting it all over the place it's never really hurt me psychologically. At the end of the day I sit down and go "meh, it was his day, that happens in cricket."
I've always found the 'killing me softly' approach much harder to take. When a guy is playing shots you at least feel in the game. It's a whole extra level of demoralising when you're facing someone who will just bat, and bat, and bat some more. They make you feel like a net bowler (and tbf, a lot of the greats who pump it do this as well e.g. Clarke, ABdV). You're bowling a spell to them and, while they're not hitting you all over the place, they just look totally untroubled. Then they dance down the track twice in an over, out of nowhere, just because they can. Then go back into their shell for a bit. You think, "sweet, I'll just plug away on a length, stick to the plan." But nope, they'll leave, block and nudge ones all day - and make you feel like you're being hit for four every time they do. There is nothing you can do to make their life difficult.
Effectively it doesn't even feel like a contest. When you're being belted, you're in a contest - even though you're losing. When you come up against a guy who's just too good, it stops feeling like a contest entirely. And that **** gets real old, real fast.
