Mavs' new course and Rangers on a heater

SportsDay Insiders Kevin Sherrington, Evan Grant and Mike Curtis discuss the arrival of Dusty May as the 11th coach in Mavs history. Mike notes that he comes with a reputation as a communicator, and he demonstrated those skills in his introductory news conference. Now, if he can communicate with Kyrie Irving, it's all good. Mike also tells us whom he expects the Mavs to try to sign as free agency kicks in. Kevin apologizes for writing that the Rangers are probably going nowhere at the trade deadline. Now that they're in first place after sweeping a four-game series in Toronto, though, is it sustainable? Evan tells us what needs to happen.
