They gave up Powell and got improved version in Beal + John Collins. That's improvement. Plus they finally have backup for Zubac in Brook Lopez.
So they defenitely significantly improved their depth and added much needed depth. Size was main thing they were destroyed on past years. As soon as Zubac sat.
Clippers would have old team regardless, they just double downed on it and added more qualify veteran options.
Kawhi was injured 40 games last season and they still won 50 games, so adding more options will help them out for regular season if Kahwi goes down a while again. Aslong as he is back to finish season in play offs, they looking good.
