After season, can we please give Incognito a try?

Our offensive line is in shambles.  Can we please sign Incognito after the season with a blunt conversation that you do anything like you did before and you're out of here being a part of the process?If he messes things up, cut him!  The guy's been out of the league for over a year...it that ain't a wake up call, nothing is.  There seems to be no downside and a great deal of upside to getting him for this team.
