It could be something like:
Minny receives: Langford, Poirier, Memphis 1st
Houston receives: Covington, Theis
Celtics receive: Capella
Keeps the Celtics core while upgrading the center position.
clever idea
but doubt this is what the Rockets are looking for
A player like Hayward is probably who they want. Capela for Covington and Theis is a downgrade for them
I've heard this is exactly what the Rockets are looking for: a high level defensive wing who can shoot the 3. Hayward is a playmaking wing, not a great shooter or defender (although good at both). Also, for them to take Hayward, they would need to include PJ Tucker. I don't see them doing that.
Theis is a downgrade, but I think they are committing to small ball right now. Theis is a rotation big who can give them some good minutes. They could take Kanter instead.
I don't think I would give them Williams if we had to include the Memphis pick.
