More ways to define tough.
Garnett was tough, but he wasn't physically imposing, he was just fantastic on defense, and gave it his all, he also talked a lot of trash and never backed down.
Kevin Love is a soft player, but his rebounding is tough. Defensively he is weak.
Marcus Smart is the toughest player on the Celtics, he is hard nosed, go after everything, and never back down guy, but as good as his defense is, players still burn him, partly because players at certain positions are so fast, that nobody can really stop them.
Toughness is a loose term.
IT is tough too. Bradley tough.
Paul Pierce is tough....Ray Allen as smooth as it gets, but tough player too.
You don't need to be a trouble maker to be tough.
