Ravens coach John Harbaugh said he was generally pleased with the first practice. "The lack of heat helped the guys, but they're in really good shape," he said. "It was a tough, demanding practice, and nobody had a problem." … The Ravens have shifted Ryan Jensen back to center and offensive guard after having him work at right tackle during the offseason. Jah Reid is competing with Rick Wagner, the projected starting right tackle. … U.S. Army Brigadier General John C. Thomson III attended practice as a guest of Harbaugh and spoke to the team. "He had a wise word for the team, just a tremendous message for the guys," Harbaugh said. "That was a great way to finish up our first practice."
