Again this is just pure speculation...Im just trying to gauge value here. Drop the pitchforks.
If the Celtics really do intend to become sellers, moving jrue and KP is probably top priority this season. BUT with the Tatum injury you are likely canning all of next season and then you don't know what he looks like when he returns. I think Austin and White are similar in terms of talent level but White is just a much cleaner fit due to the defense. BUT I do also believe Austin has even more room to grow as a longer term piece and is 4 years younger than White.
Still think Boston doesn't do it but I do believe this is an interesting exercise to see what Reaves could net on the open market
