^^ Thats easy to say when you're just a spectator.
it's also easy to say when you made that actual mistake and paid the price for it.
other people can do it, therefore he should be able to do it too. it's easy to say and just as easy to do, you just do it, it doesn't take a particular effort, being smart enough does the job, then you get used to it and grow into being comfortable. Of course it's not done overnight but it's like for people who want to quit smoking, you just have to stop doing it, and it takes willpower more than anything else. I never said it was easy, but at this level, these guys should be prepared and ready to fight anyone, because they're professional, their job is to do it.
If you're a supervisor and your boss tells you to fire a friend of yours, you just do it, maybe you try and put a word in for the dude, but ultimately, you're going to do it or take the chance to lose your job. That's being professional. And when you're working in the world #1 company as an "executive", you're expected to be professional.
nothing to do with easier said than done or whatever, that can apply to small/amateur leagues maybe, but not when you're on top of the world.
