I think Danny and Brad want to add someone, whether it's with the TPE or with picks or even a trade. I think the challenge is finding the right player at the right price, without weakening other parts of the team. I think they weren't expecting to lose Hayward, so losing him has put a lot more on the shoulders of Tatum and Brown, not just offensively but defensively. Brad tried to make up for Hayward's loss by trying to convert Theis into a stretch 4 to replace Hayward more so on the defensive end, also to try and accommodate Kardashian, who I think hasn't worked out as well as they thought he would as a starter. Then Kemba's injury meant he hasn't really been a contributor offensively or in terms of running the team, which has put a lot more on Smart's shoulders.
Also I have a feeling Brad is using these games as experimentation to work out his best combos or worst combos, even at the cost of losing games. I don't think he or Danny are overreacting the way we as fans are, but the risk in that is always your team starts to get disengaged, especially the bench guys who sit all one game then play 20 min the next and then sit the next. Or start one game then don't play the next. Unless they're all tuned in to what's going on it could cause confusion, and could cause the top guys to get disheartened. That's what I'm reading from some of the comments from Jaylen recently.
