I'm not an expert, but I think the issue is that we have two subpar linemen next to each other in Chibane and Macky, and a third in Hay that's not very good or a very smart player I don't think either. Last season we could get away with Chibane because he was bookended by two solid guys in Pugh and Bart. It seems to me, and I haven't been tracking this directly or anything, but it looks like when Macky gets beat that he gets beat on his left shoulder. He needs some help, and it's not coming from Chibane, because Chibane needs some help.
I'm extremely concerned that Macky didn't play better against a subdivision team like this.
