Yes considering OKC wouldn’t trade SGA for Tatum straight up. SGA is the epitome of the modern PG you can win a championship with (that isn’t named Steph Curry). Collins is just a cherry on top.
Tatum is an interesting piece because he has rare position versatility with his combination of size and shot making. But because we have Jaylen This also makes him easily replaceable. Jaylen can slide to the 3, we get another good 3&D SG to replace Tatum’s shooting, and now we have Collins as a PF.
This trade never happens, because SGA is better than Tatum currently. But regardless this team is at a fork in the road and needs to decide what its identity will be.
