You're proving my point without realizing it
They didn't try to go after big names. Hell, they didn't even go after semi big names That's my entire point. They were a playoff team for years, yet never even tried to take the next level in going after a big name to put themselves up there with the elites. That was one of the biggest complaints about them. They wanted two first round picks to move up to to draft Zach Collins when they could have used those picks to go after a more ready player. They gave up two picks to go after Robert Covington of all people when they could have been used elsewhere.
Milwaukee did everything that they could to put a contender around Giannis. NO did the same thing with AD or at least tried, so the narrative that Portland couldn't try and do it either is complete bullshyt. You're acting as if we haven't seen other small market teams like Cleveland (even after Bron left) and NO swing for the fences to keep their star player happy.
If your star player actually wants to stay and be there, then that's on you to try everything in your power to put a contending team around them, which is what Milwaukee has done twice and all done Giannis tenure.
