Would you be able to not flinch if someone was about to throw a basketball in your face? Would you be able to 'know' there's nothing to worry about? Can people get inside your head with a little face to face trash talk? Is criticism tough to take? Do you take advantage of it if you are mentally tough? If you aren't, do you think other people take advantage of it in you? I should clarify. Mentally tough doesn't mean "I have no emotions", it means you're confident in yourself and your abilities, despite the circumstances. It also does not mean arrogance. What do you think floodies?
