Yeah, I don't know of one GM who ever thought "Gee, we're really close to being a Super Bowl contender. What move should I make to put us over the top? I know, I'll get an interior lineman."
Edge rusher is the second most important position in football. We were lacking one last season. Gute had an opportunity to address it and failed miserably, unless he drafts an elite pass rusher in the first round and not another "project with upside", which is a euphemism for jobber.
