Cornerback DeAngelo Hall and defensive coordinator Jim Haslett got into a contentious exchange Tuesday over pass coverage instructions, a development Coach Mike Shanahan followed by meeting privately with Hall and singling Hall out at a team meeting Wednesday morning, according to three Redskins employees familiar with the events. Hall and Haslett have a good relationship and there should be no lingering animosity as a result, the employees said. On Wednesday morning, Shanahan singled out Hall at a team meeting at Redskins Park, citing a need for better communication among players and coaches, the three employees said.
