Why Cavs? Builds long term team for future. New Cavs core is -

PG Garland, Jerome, CPJ SG Mitchell, Merrill, Christie SF Bridges, Okoro, Tyson, Travers PF Mobley, Wade, C Allen

Only think left is to draft another big or find vets to fill that depth

Why Lakers?

PG Reaves, Mann, Vincent SG Strus, DK4, Reddish SF LeBron, lewis PF Rui, Vanderbilt, Niang, Wood C AD, Hayes

Strus adds another starter to spread floor he may bring best out of Vincent having a familiar face. Mann adds PG depth for this season and Niang another stretch guy like Channing Frye on Cavs championship season

They do lose Christie but Strus replaced him better imo. Both JHS and DLO not in long term plans so this is a Lakers upgrade imo

Why Hornets?

Easy, two expiring deals and 3 picks. Miller and melo are more of their core And LeVert can help in meantime the perfect deal for a rebuilding team and they can use cap next year to get another starter.
