Several NBA teams are interested in Kevin Durant, but suitors have one prevalent concern about trading for the Brooklyn Nets superstar.

According to NBA insider Marc Stein, teams couldn't help but wonder whether they can keep Durant happy and motivated to stay with them long-term. As reported earlier, if the Nets couldn't keep him happy despite giving in to all his demands, how can they expect him to stay and not do the same thing he's doing with Brooklyn?

The perpetually title-or-bust Heat, not surprisingly, are all-in on scouring the league to try to manufacture extra first-round picks to boost their chances of completing a trade for Durant or Utah's Donovan Mitchell. But more teams than not are asking themselves this question: If we trade for Durant, how long before he wants to go somewhere else?

That is a valid question indeed. Sure, any team who trades for Kevin Durant will get his four-year deal. That means he'll at least be under contract until 2025-26.

However, that not the real issue. What if KD becomes unhappy again and decides to sit out and come up with several reasons not to play until he's traded? That is a real possibility that could be a major blow to the team trading for him.

Not to mention that the Nets are asking a lot for KD. If Durant ends up forcing his way out once again, it's unlikely his new team could recoup the assets they gave away for him.

The truth is it's really risky to trade for Durant. While there is championship upside, it is not even a guarantee that he'll stay long-term to his team to make that a reality.
