One can argue that Dwyane Wade is the leader of the Miami Heat. One can also argue that LeBron James is the leader of the Miami Heat. However, no one will say that Chris Bosh is the leader of the Miami Heat.
What Wade and LeBron bring to the table is very obvious, they bring scoring, defense, and leadership.
But what does Bosh bring to South Beach? He does bring a rebounding presence and a great post game, but he’s never been to the second round of the playoffs.
