for whatever reason, blocking back doesn't seem to work very well to me. Even when I had 5 or so in it, my FB would stand there and wait for somebody to get through the line, except on occasion he'd bust through the line and block the wrong guy. For this reason, I'm also skeptical of the spot blitz SA. I think you're better off with good attributes and good vision, and then VAs that improve situational blocking, rather than helping with vision checks. I just don't believe the vision checks for FBs really include everything they should.
