The concern is whether DWade will still have his explosive by the end of the playoffs. 100+ games to get to the Finals is a lot of wear and tear and opportunity for injuries for older guys.
He looked great in the regular season last year too. The question is whether he finishes the regular season and into the playoffs healthy. What he needs to do is skip the back end of the b2b, and some games on long road trips. The Heat don't need him to be a top 2 seed in the East.
