I've said it multiple times before. People don't seem to understand what a linebackers' responsibilities are and what good linebacker production looks like. Something which makes no sense given this team's fans have been watching great linebacker play for such a long time. Smith is already pretty damn good and has been making those splash plays people were bitching about wanting from him.
IMO, I think too many idiots put Urlacher type expectations on him. So they're not seeing interceptions and now think he isn't all that great.
