Chalmers will be fine. Point Guards have a tough time playing with Lebron because he wants them to just be spot-up jump-shooters and that's not the way it's done. He had a bad series this year, but look at the games and series where he showed up and actually won the series against OKC when Lebron cramped up. Manu had a horrible series for the Spurs last year, but they didn't dump him. Kyle Lowry didn't come to Miami because he didn't want Lebron to kill his career. FYI, there's going to be a problem with Lebron and Kyrie, they both like the ball.
