I just think this is such a weird conversation, honestly.
How can you not be concerned about the defense right now? Most of us aren't saying the defense is GARBAGE. We're saying that we think it could be bad, and then giving specific reasons why. Unreliable corner play, inexperienced defensive coordinator, questionable defensive scheme, no proven linebackers anywhere on the roster (except for Kiko, who is being asked to do things he's not good at), aging pass rushers, etc.
How can you not be concerned? I gotta be honest, the two best things I saw Thursday night were our first and third round draft picks. Because Minkah looks like he just might be the guy that I hoped he was when we drafted him, and Jerome Baker actually looks like he can play football. We need quality play at FS and LB so badly it's almost sad.
