Dalembert is such a bummer option. But I'd much rather bring him or Jermaine Oneal in to back up Tristan for the rest of the year than waste either our Memphis pick or Dion on a trade when there will be much, much better targets this summer.
We are really fortunate that, while Tristan isn't the long term answer at center, he's equal or better to the task at the position than Andy was. So for this season, our aim is to shore up our backup center position, unless a really good option is suddenly available.
Then, in the summer, you look for your long term replacement that sends Thompson back to a bench role.
