Dennis Schroder is just looking for a bigger contract than what the Lakers is offering him, perhaps he just want to maximise his potential while he is still healthy. But obviously, LA doesn't want to provide or at least they don't have the capacity right now to offer it to Dennis because of salary cap.
Schroder just isn’t worth the money that was spent on him or that he’s seeking. The Lakers grabbed him and Harrel because they had roles they wanted to fill and needed talent. They both vastly underperformed and like KCP, their contracts needed to go. I feel like the Lakers aren’t carrying a bunch of dead money around now (except Luol Deng’s contract) and are in a pretty good place to sign more superstars when Westbrook and LeBron get too old for title runs.
