It would be shocking if the Miami Heat didn't explore adding another big man between now and the start of the season. But even if they did, you'd have to imagine they're going to need to make some sort of move to solidify their frontcourt depth at some point soon. Theoretically speaking, Nikola Vucevic could be a natural potential fit for the team.
Whether they can find a way to get into the market for him or not remains to be seen, but there's a very clear path toward the Heat pulling off a move. Of course, it would revolve around finding a taker for Terry Rozier.
