Eddie Jackson has joined the Baltimore Ravens on a one-year deal and expressed enthusiasm about the depth and competitiveness of the team's defensive backfield during training camp. The Ravens' defense, which recently lost former coordinator Mike Macdonald to the Seahawks, is now under the guidance of 32-year-old Zach Orr, who has received strong endorsements from players like Justin Madubuike and Roquan Smith. Despite offseason changes, including key player departures, Smith is optimistic that the defense can improve upon last year's historic performance, which included leading the NFL in points allowed, sacks, and takeaways. The addition of Jackson and the presence of emerging talents like Kyle Hamilton and Nate Wiggins enhance the team's defensive prospects. Players believe that Orr, described as a 'defensive mastermind', will effectively leverage their strengths to maintain a high level of performance. The Ravens' defense aims to build on their near-Super Bowl run from the previous season, driven by a strong mindset and camaraderie.
