Flipping TJ to keep Oubre makes no sense.
Oubre will want to get paid at the end of the season whereas TJ is tied up long term on a great contract and TJ is a much better player than Oubre.
I don’t think Oubre will get more than Warren and Warren cannot defend. I think Oubre might be a better prospect long term. He’s had a below par season but was actually very good last year.
