OK, that headline is a bit misleading. LeBron James isn't upset with Mario Chalmers or anything. James only joked after Tuesday's practice that if Chalmers wants less grief from James this season then Chalmers would have to grow up. Chalmers mentioned on Monday that he liked it if James toned down his on-court admonishments this season every time Chalmers makes a mistake. We all know James' "Chalmers face." James didn't have much sympathy or Chalmers on Tuesday.
