Nets take a punt on Lively with his messed up ankle as a young replacement for Claxton (Day'Ron Sharpe would be an excellent backup as well).
Celtics' part is more for the future, taking a punt on Drake Powell, see if he can turn into a solid rotation piece for them, and signing Mitchell Robinson and drafting Chris Cenac Jr they don't really need Luka Garza.
Knicks get Luka Garza as extra Mitchell Robinson replacement.
Mavericks turn Derreck Lively who is great but injury prone and they kind of replaced in the Santi Aldama trade into some future seconds, a first in next years draft, and a Ben Saraf who I believe could be a great young guard for them long term.
Thoughts?
