Why the Lakers do it
First KCP would have to agree and if he does, they get a culturally tough player who you a team can allow to beat the drum, to give them a real attitude. They decrease their roster by 1 players. They increase their roster spending by $4.9M. They increase their win probability by 3.
They add the following players to their roster:
Marcus Morris ($15.0M, 1yrs remaining)
Why the Knicks do it
The return is more about taking a flyer on Kuzma, he was the best player the Lakers drafted in the year of Lonzo. KCP is for matching. He'd hopefully see the pine in blow out scenarios. They increase their roster by 1 players. They decrease their roster spending by $4.9M. They decrease their win probability by 3.
They add the following players to their roster:
Kentavious Caldwell-Pope ($8.8M, 2yrs remaining)
Kyle Kuzma ($1.9M, 3yrs remaining)
