You have ti backwords. IT is a support player, not a foundational piece which others play off. Reke is much closer to Parker/Westbrook than IT. Those two teams allow the support players to play off Parker/Duncan and Durant/Westbrook, they don't bench Westbrook and play off Sefalosha. You don't bench foundational pieces and turn support players into go-to players.
You're also ignoring the entire defensive setup of these teams. They have one go to guy in the backcourt, and a defensive specialist. Reke is our backcourt go-to guy, not IT or MT. So if you wanted to emulate what SA or OKC does, you'd start Reke NEXT TO a defensive specialist, have a defenders also at the 3 and 4 to round out the lineup with Cuz, and bring firepower off the bench. Not bench a go-to guy and go instead with a non-defensive backcourt.
I don't think many here actually understand the theory behind what OKC and SA do and don't understand they pick two go-to guys, and round out the starting 5 with defensive role players.
Then how does their bench work? Where does Thornton fit in? With Evans off the bench you maximize the team's scoring and talent. Tyreke will still see his 35 minutes, you just minimize the time he has to share the court with IT and Thornton. Tyreke can just play like he did in his rookie year, control the offense and win with lesser talents (bench players) around him.
Did you enjoy an IT/Jimmer backcourt? That is what you'll see at times if IT comes off the bench.
