The Dallas Mavericks are learning the harsh lesson that Anthony Davis is injury-prone and struggles to stay in the lineup, and this is something that they should've known all along. This hasn't been a secret over his career, as he struggled with injuries in New Orleans and Los Angeles, and the injury bug has followed him to Dallas.
One of the reasons that the Mavericks traded Luka Doncic to the Los Angeles Lakers for Davis was that they predicted that Doncic's body may break down, but the player that they brought in for him has a much more severe injury history.
