Our depth seems to be a bit less than anticipated, because of the release of Walker, the disappointing career-start for Scheierman and the lack of offensive progress for Springer, Walsh and Tillman. In other words we could use an extra low-usage defensively strong veteran who easily fits the team.
The best option on the table at the trade deadline might be our familiar Javonte Green. The Pelicans have had a bad start of the season and considering the very strong competition they might not be able to even reach the play-in. A good team to do business with. A veteran on an expiring contract in Green doesn't have huge value. Perhaps Scheierman, Tillman or combined with a second round pick?
Then our playoff-ready roster looks like this (where Green and Kornet are merely injury-covers):
Guards: White, Holiday, Pritchard
Forwards: Tatum, Brown, Hauser, Green
Bigs: Porzingis, Horford, Queta, Kornet
