I mean the one time he played with an elite defensive center we were pretty close.
You built around your superstar, every team does this. What you don't do is trade three picks to get an All-Star-level player that plays the exact same position as your current superstar player. That move was 100% a gamble on that Murray could provide similar value at the 2 than at the 1 and that has been proven so far to categorically not be the case. You can't blame Trae for that, that's on the front office. There is a huge gap between the talent level of our top 2 guys and the rest of the team, but sadly the top 2 guys value drops when they have to share the floor. That, along with lack of depth + a lot of injuries, is why the team is "underachieving" relative to their perceived talent level.
I will add, to built a winner you need to be absolutely elite at least on one end of the floor. Trae has shown he can consistently lead elite offenses even with very little in terms of supporting casts. He is a no doubt about it top 5-10 offensive player in the NBA, he was consistently top 3 before the DJM pairing. There is a literal handful of guys in the entire NBA you can replace Trae with, the same is not true for Murray.
