I think the issue is a lot of folks still haven't wised up and appreciated him for the really promising 2-way player he is. And I don't even think he's shown all he can do yet either.
Again, just eye test watching him, but he's been able to flex onto guys like Mitchell/Steph/Luka with tremendous success. Does he shut them down? No, but no one does. I think he absolutely puts a better effort on them than virtually most of the league.
This might sound crazy to some, but I kinda see Keegan Murray as the KINGS version of Scottie Pippen.
I'm not suggesting he will end up as a top 50 player like Scottie Pippen or be a vital part of winning 6 titles, but I definitely see some similarities.
They are of similar height and weight. They both entered the league at 22, with Keegan being slightly ahead of where Pip was after season #2.
Of course, we know how crazy of an athlete Pippen was and what an elite defender he became. While Keegan isn't the athlete Pippen was, I think his defense can develop to a level somewhat close to Pippen (sans the crazy athleticism) if he continues his current path.
Remember, Scottie Pippen didn't really begin to become recognized league wide as a defensive stalwart until his 4th and 5th seasons in the league. Keegan is still only in year 2.
Offensively Keegster doesn't display the highlight reel dunks that Pippen did, but he has already shown to be at least as good a perimeter threat, if not more dangerous, and is still developing the other parts of his offensive game. Whether he gets it all figured out eventually or not, the tools are there.
IMO, by year 4 or 5 Keegan just might be close to the same level of a 2-way player Scottie had developed into. To me he's a bit Scottie Pippen mixed with the demeanor of Tim Duncan.
