Wade is, without a doubt, in the top 5 in the league.
That being said, he would not have won more than 3 interchanging with Kobe on the Lakers.
Also, I think that it seems obvious in retrospect the Lakers made the right move trading Shaq in 2004. You think they would've won 2 more championships when they couldn't even win in 2003-2004 when Shaq was still in his prime? Shaq was asking for a 6-7 year contract in 2004, which would've meant they had THIS Shaq to this day, and most certainly would've been mediocre today. I think they made the right move.
