Very true. Parsons is much more valuable on a D like the Packers who just need him for the one thing he does very well. As opposed to the Dallas D that needed him to be the savior.
You can't grade any trade that includes draft picks who haven't been drafted yet, LOL. Dallas can still come out fine, they just have to use the draft picks wisely.
I disagree with you on one thing - Packers aren't winning a Super Bowl either - they got the wrong QB for that. Love isn't the guy to take them there. I don't believe in him at all.
In a few years, neither the Packers or Cowboys will have won any Super Bowls. The Packers will be paying an aging and breaking down one trick pony a ridiculous amount of $, and hopefully the Cowboys have some good exciting players from the picks.
