The three-day draft will start with the first round on May 10. The Ravens currently have only four selections after trading a fourth and fifth-round pick to the Jaguars for offensive tackle Eugene Monroe and a seventh-round selection to the Indianapolis Colts for guard-center A.Q. Shipley. However, they are expected to be awarded as many as four compensatory picks at next month's owner's meetings because of their numerous free agent losses last offseason, which would bring their total to eight.
