I agree. The initial timeline was ridiculously short compared to what it's had to be. We eventually found it, weeks after it would have made sense for him to return, that there was a setback. That annoyed all the fans because people undersatnad a set-back but they naturally see radio silence when news is due as lying by omission. You can argue that it makes sense for the franchise to do that, and cool, but from the subjective fan perspective they had to know that hiding the problem was more annoying than just saying ''yeah there's been a set-back, it will take longer''.
Then, despite that backlash, despite the unpopularity of the move, they do it again with - as you point out - saying there would be an eval in 8 weeks and then we didn't hear anything until it was revealed he was playing 5-on-5 about 13 weeks later. And now complete silence; the team is putting out clips of his dunks, he's attending the games, and everything we're hearing from what leaks are happening is that he wants to play, and they're holding him out for... why?
Could he get injured again? Sure, but if we're at the point where you're so scared of him getting injured again that you're going to refuse to play him in winnable postseason games then what's the point of even having him?
Unless there is a valid medical reason to keep him sidelined, play him. Play him now before it's too late and we're out of the playoffs.
