Kapron Lewis-Moore played as a 3-4 end in the Notre Dame defense, which was surely something that made the Ravens excited about him. Lewis-Moore was considered a mid-round pick in the draft until the BCS National Championship game when he tore his ACL. Lewis-Moore has intriguing potential though, and will have time to recover before he is asked to contribute.
Lewis-Moore has experience as both a 3-4 end and a 4-3 defensive tackle and could project to either position in the NFL. Because he was injured only a few months ago, he will likely take until at least training camp before he is ready to play. However, don't be surprised if he starts training camp on the Physically Unable to Perform (PUP) list and ends up getting stashed on injured reserve for the year.
Lewis-Moore will likely be behind Chris Canty, Marcus Spears, Arthur Jones, Pernell McPhee and even DeAngelo Tyson on the depth chart. Because of this log-jam and Lewis-Moore's injury, don't expect anything big from him this year. He is likely a project that the Ravens felt like they should invest in for 2014 and beyond.
This could actually be seen as an extremely smart move because the Ravens are already going to struggle to find room for all of their rookies on the roster. If they stash him on IR, there's a greater chance they can keep more of their young guys.
