Yeah but we're talking patterns over hundreds of games. We get a pretty good idea of who handles pressure and who doesn't when these guys play enough matches. I agree that getting out for 10 doesn't mean you got out because of the pressure, but performing under pressure is rare to do unless you're mentally tough enough. At least to do it enough times to get a reputation.It's defs a thing that some people deal with pressure better than others. What's harder is to say who's actually good at it based on a couple of performances. Lyon for example is a suspected bottler. That fumble at headingly was ATG bad. However he could've easily had Stokes LBW or caught on the boundary like 3-4 times and then he'd be the hero and Stokes wouldn't have played a clutch knock.
You get a good nut in the final and get out for 10 doesn't mean you got out because of the pressure. Likewise, just because you performed under pressure doesn't mean it was your mental toughness or whatever that made you do well, it could just be down to luck/skill/the opposition playing poorly/stars aligning.
The best you can do is make educated guesses and that's what the point of this thread is.
