Free agency isn't over, exactly, but just about all the exciting stuff has already happened, and we had plenty of excitement in the NFC North. Let's go over some of the key additions and subtractions in the North. 

Vikings

• The big news is that Kirk Cousin left for Atlanta and the Vikings are already making moves to try to get a QB in the draft. Cousins was an above average QB a lot of the time and a very below average QB some of the time for Minnesota. We don't know for sure whether the Vikings will be able to replace Kirk with a better QB -- grass ain't always greener -- but we know whoever they replace him with will be put into a pretty good situation right away with plus coaching, a plus offensive line, and two first-round picks at WR. 
• The team also let Danielle Hunter hit the road, replacing him with Jonathan Greenard and Andrew Van Ginkel. Greenard isn't quite at Hunter's level, but he has been a very good NFL player when healthy. Van Ginkel, a former Badger, is probably about average as a pass rusher but brings a lot of other skills to the position that you rarely see in an edge rusher. 
• Almost forgot. They also signed Sam Darnold to either be their bridge QB or sacrificial lamb. They hope he can maybe be their Baker Mayfield, but it's likely he'll be more of a Nick Mullens 2.0. 
• In the most annoying move of the off-season, Aaron Jones chose to not have a chance at playoff success next year in exchange for an extra $1mm. He signed with the Vikings as I'm sure you've heard. 
• The Vikings also filled some other holes at linebacker and o-line, but nothing that really moves the needle a ton. 

Bears

• The Bears also made a big QB move, trading Justin Fields for a copier that could convert into a copier with scanning capabilities in 2025. They will likely replace him with Caleb Williams. Godspeed. 
• Their other splash move on the trade market was trading for 57-year-old Keenan Allen who makes $40mm per year (all numbers are approximate and adjusted for Bears terribleness). It's definitely true that Keenan Allen and DJ Moore will ease a rookie QB into the league more than like Velus Jones and Dante Pettis would but you just have to laugh at trading draft capital (when you'll be left with four (4!) total picks) and then overpaying an already slow receiver who was drafted the same year as Eddie Lacy. Eddie Lacy has white hair! 
• In other hilarious news, the Bears made the first move of free agency by signing De'Andre Swift to a three-year $24mm deal. You might know Swift from his history of being terrible for the Lions. The Lions, who drafted him high, ditched him last off-season and immediately spent a top-12 pick on a running back and signed David Montgomery. Montgomery had about the same number of yards as Swift last year and twice the touchdowns. He signed a three-year $18mm deal with Detroit after the Bears chose not to re-sign him. You can't make this stuff up. 
• The Bears also added Gerald Everett at tight end, former Packer Jonathan Owens, and Kevin Byard. Meh, double meh and triple meh. 

Lions

• Imagine someone telling you a year-and-a-half ago that the Bears and Vikings were looking for a new QB but the Lions were happily going into another season with Jared Goff and might even extend them. And that their biggest move in free agency was signing a nose tackle (OK, you probably could've guessed that). 
• The nose tackle is DJ Reader who has been one of the best run stopping defenders at any position over the past five years or so. Reader would be a great get for just about every team, but just feels superfluous to this Lions team. They already had a great run defense. They need to defend the pass better. They need another edge across from Aidan Hutchinson. Reader will likely be a pro-bowl level run stopper in Detroit, can't really argue that. I would've loved him in Green Bay. Just have to question the value of adding him to this Lions' team. 
• I do have to admit that the Lions finally did try to improve their pass D with a legitimate move. They traded for Tampa Bay corner Carlton Davis. Davis broke onto the scene in the Tom Brady Super Bowl era when he was widely recognized as one of the premier man corners in the league. He hasn't really gotten that level of recognition over the past two seasons, but he is still a great man corner. Which leads me to guess that the Lions may be going all in on Aaron Glenn's original plan to play press man, try to get pressure with four and stop the run with a heavy line and a heavy box. It works in New Orleans. Now we'll see if the Lions can pull it off, finally. 
• They also replaced departing tackle Jonah Jackson with Kevin Zeitler (ancient) and Graham Glasgow (JAG). They'll probably still have one of the top-5 or so offensive lines, but it'll be a little worse.
