I feel this is a much more realistic trade imo. Pacers can offer more picks. While if GSW would simply contribute to a 3 team trade. They wouldn't get Markkenan, but a great scrappy Klay replacement again with Sheppard and a future replacement in Draymond Green. Then don't forget all the amazing things Turner would do for GSW at 3. This trade would actually much better suit GSW.
As the Pacers move off some young future contracts to have to worry about signing and get the big perimeter SF/PF they need in Markkenan and the replacement C they will have needed after this year in Turner. Pascal plays better at the C, so this is the perfect trade.
