I have to admit that trades that not that long ago seemed no brainers (ideas involving Davis and Leonard for packages involving Brown and/or Tatum) are much less attractive now. As Davis will not be available until 2019, we will have even more idea on just how good Brown and Tatum can be and if Davis is a piece the team needs (he will always be desirable but not necessarily needed).
Leonard has so many questions now about his injury and commitment, I would baulk at any trade until his fitness and dedication are clear. Of the two, a fit and focussed Kawahi would be my preference by the smallest measure as I think he would be a great fit. Not really that much in it and I can see sense in keeping this squad together next season and seeing if they can achieve the ultimate goal without a trade.
What happens with Kyrie and Rozier is a whole other debate. The kind of problems it is good to have.
