The primary question is: is Incognito an upgrade over what we have now?
The next question is: Is the upgrade significant enough to accept the initial negative press?
If both answers are yes, bringing him in begins to make some sense. First, it would be a Haynesworth like Contract. He's easily gotten rid of with no tangible $$$ impact if his play isn't up to snuff or he is a disruption to chemistry (I'd bet the mortgage payment he's likely to be a good teammate -- he must be desperate to reestablish/redeem himself. Need is the mother of invention as well as change). Second, "womanizer", "jerk" etc are not valid reasons to outright dismiss bringing him in. This will come as a shock to some fans but currently, likely, you root/rooted for/like/liked pro athletes, among others, that fit that description to a T. Third, as crappy as his locker room behavior seemingly was, his locker room behavior may have been what he was weened on. This stuff have been part of football in some corners for a long time (probably a lot longer than it should -- that's a different discussion). Lastly, and maybe more importantly, what he did makes him beyond redemption?? People make mistakes, sometimes really bad ones. Incognito made some really bad mistakes. However, the mistakes he made, IMHO, do not equal him being barred for eternity from his profession. This guy has been harshly punished for his transgressions in more ways than one. Some might argue punished far beyond the crime (again a different discussion). Is there no room whatsoever to allow someone, who made mistakes like he did, a chance at redemption?? My beliefs of erring/the imperfections of the human condition are not rigid.
