Heat will pursue Kevin Durant in free agency

With the salary cap set to spike by more than $20 million to an estimated $89 million next season, the Heat has left itself flexibility to accommodate the salary of any of the top-tier free agents --- from Kevin Durant to DeMar DeRozan to Al Jefferson.

But signing a top-tier player would likely mean the departure of Hassan Whiteside as well as Dwyane Wade needing to make a financial sacrifice.

One thing is clear: The Heat intends to make a long-shot bid to lure Durant, who sold his Miami condo earlier this year.
