There's a few things unrealistic about that.
1. You can't trade Avery Bradley in the first deal until he accepts his qualifying offer, which certainly wouldn't happen before the draft, and could take several weeks, or even months. That means that we'd have to pick for Minnesota, and hope that that Bradley agrees to later forgo restricted free agency and sign for the QO. That's not happening.
2. Houston isn't going to deal Asik for Bass and a couple of second rounders. If they move Asik, it will be for legitimate assets, or cap space. This deal gives them neither.
3. We would have significantly less than $12 million in cap room, when you take into account cap holds, etc. We could attempt to use the TPE in a Deng sign-and-trade, but we won't have outright cap space.
4. We'd have to renounce the MLE if we used cap space, and would only have the much smaller "room exception" to work with. That's probably not enough to sign Humphries.
