I don't think Evans will be able to score in as many ways as Wade can, Wade can score in the same ways that Evans does and even moreso with his jumper and explosiveness, and he has better off-ball ability than Evans because of his superior athleticism. Even with that said I think Miami overachieved quite a bit that year, plus they had the refs really in their back pocket and Shaq as a decoy.
While players like Kobe, Wade, and LeBron are most effective with the ball in their hands they can still do stuff off the ball and they don't need to pound the ball as much as Evans does to get where they need to.
I'm not really saying they just need some defensive role players, I'm saying they need to be a defensive oriented team and get an all-star level post scoring big.
