Lots of people on this board don't like Marcus Peters. I get that. I'm not even going to try and convince you otherwise, because its irrelevant. You don't like him. You don't have to. There are reasons not to like him.
But Marcus Peters is a playmaker on a defense that had too few playmakers to begin with.
If Eric Berry doesn't return next year at his 2016 level of play, the Chiefs defense will likely have only the often injured Justin Houston as a true playmaker. For a defense that already struggled, that's not good.
Add to that the fact that the secondary was already shaky even with Peters playing at a top 10 level and you have the ingredients for the defense to take an even larger step back next season.
Like I said before, this is a terrible football move. It will hurt the Chiefs in football ways. I get that a large part of the fanbase wanted him gone, and that's their right, but this move is one that was done by a franchise that has already experienced the Trent Green-Priest Holmes-Tony Gonzalez years of big offense, no defense, lose a playoff game in which neither team punts type of teams.
If you're a free agent looking to win, that's something that you may weigh in your decision from a football standpoint, given that this team hasn't won a home playoff game in more than two decades.
