It's one thing to be a UFA like Brunson but another to have to give up assets that SAS actually wants or finds value in. As usual, Knicks have little value except Tobbin, Quickley, DAL 2023 FRP and their own to mortgage. The reason why there is so much hype on this here is it actually makes sense from both sides more so than other trades.
The only big question left is why was it leaked to Fischer before a woj or sham bomb... That is what gives it pause.
