Cool to see DT Casey Walker back with the Patriots. I was disappointed when the Ravens signed him off the practice squad last season. I think Dominique Easley, Malcom Brown, Sealver Siliga, and Alan Branch are essentially locks at defensive tackle (Branch less so) with Chris Jones likely staying on the PUP list, with Antonio Johnson, Zach Moore, and now Walker competing for the last two spots. I'd like to see Moore earn the spot since he's a home-grown talent, but I think he's more likely to head to the practice squad.
