Doesn't seem like it's much of a negative, if Berger's sources are to be believed:

"Oklahoma City sent Ibaka to the Magic for Victor Oladipo, Ersan Ilyosova and the rights to No. 11 pick Domantas Sabonis, league sources confirmed.
The first thing to understand is that the trade never would have been made if there was a chance it would have affected Durant's decision in free agency; it won't, said a person close to the All-Star and former MVP."
That really doesn't make any sense at all. Durant has said many times that it's going to be a basketball decision, and he's going to find a place where he thinks he can win. He'll necessarily have an opinion on how this trade affects his team, so it necessarily will affect his decision. I just don't see this as a good move fit-wise on a team that was already having questions about fit. He's not going to want to play 4 full-time, and Kanter/Ilyasova replacing Ibaka is not going to be good at all for what was a below average defense for most of the year.
Plus, explain this to me. If they're worried about money and affording Ibaka, why did they trade for Oladipo, who is a restricted free agent the same time as Ibaka? He's going to command a major contract, too, so I'm a little confused how that really helps. It must have been more to do with Ibaka growing uneasy with his role, and they were afraid that he would demand a trade soon.
