Again, Dwyane Wade will only ever play for the HEAT. He belongs nowhere but Miami. He will retired as a member of the Miami Heat, in Black, White and Red.
I don't think the HEAT has the class to pull this off. They certainally don't have the history.
They have the only role player in the league whose been on the same team for all 10 years, Udonis Haslem.
They signed Juwan Howard, who nobody wanted, simply because they liked him from last year. He doesn't even play!
They've kept Wade all these years and he's still a ridiculously good player averaging 21/5/5 with a 24 PER (7th in league, 1st among SGs)
He's still a HOFer and can be considered the best SG in the world today. Trading his 18 million dollar contract would be pretty dumb, and plus, he's a huge fan favorite (still 7th in NBA jersey sales).
