Pierce is honest at least but selfish at the same time.
Not really what a true leader would say ever. KG on the other hand, is one loyal dude. I bet even if Pierce gets traded , he doesn't complain , does his job and tries to help our team win. Its such an admirable quality that is lacking in today's nba. Guys like Lebron James, Bosh are poster child's for what is wrong with today's nba. Guys who have no affinity with Miami except wanting to party 24/7, want max cash and play with other all stars in order to increase their chances at a ring.
Pierce isn't being selfish, or lacking in leadership one iota. He's simply being honest. I have no doubt, in his mind, this team is still capable of winning a title. This comes from a supreme confidence in his own abilites, and KG's as well. It has nothing to do with not wanting to stick around for a rebuild. He just doesn't want the team to rebuild.
Also, KG isn't sticking around if Pierce gets traded. He might finish he season, but he'd reitre at seasons end. I guarantee it.
