People use the Matthews injury as an excuse for Olshey, but I think that injury highlighted a problem with the team Olshey built. That team had little to no depth. Any injury to our starting 5 would've made us a likely 1st round exit. We had just traded for a "solid" replacement at Matthews position, and had a young player at that position who broke out in the playoffs, and we still got dominated. That was a problem with that team. With how much they got paid, it probably wouldn't have been possible to bring back Matthews and Afflalo so you would've been looking at a bench with C.J. McCollum and a bunch of mediocre fringe rotation players. Any injury in the future would've meant our team completely falling apart. Injuries happen. That team wasn't built to withstand them.
The argument I usually hear towards this is "But losing Wes was extra-bad because he was the heart and soul of this team!".... But so is Nurkic, and Nurk is better than Wes ever was. Yet we still made the WCF because we could absorb that injury. Those Aldridge-led teams were unable to absorb any injury to their key guys.
So I don't think that team was built to truly contend. I think it's ceiling was about the same as the teams that followed, and therefore, I think it was probably the right decision to trade Aldridge regardless.
Fans may have been upset but as I said, it's on the GM to have more foresight than fans. If we got back a good package behind Aldridge, it got leaked that he had turned down a contract extension, and Olshey went forward with wanting to "build around Dame" and "Get younger talent that can grow with Dame, CJ, Will, etc" then I think our fanbase would've been somewhat understanding. Obviously, Paul would've had to sign-off on it and it's definitely possible he wouldn't have.
