Lamar Jackson’s reasons for being at the Ravens’ voluntary organized team activities Wednesday were simple. “Just wanted to learn the new offense and get with my guys,” he said, adding that he plans to attend the other sessions that will take place over the next three weeks in Owings Mills. He found humor in the fervor over when or if his arrival would take place during the voluntary portion of the offseason. Participation in the practices, after all, isn’t required and not every player was there, though attendance was high for Wednesday’s portion that was open to the media. But the appearance of Jackson, who arrived ahead of Tuesday’s practice, also marked an important step forward for the 26-year-old quarterback and the organization.
