King isn't unsigned because he can't play in the NFL, he is unsigned because rosters are full of a lot of promising new draftees and UDFA's, that teams have committed to look at. Like many have said, he is a Free Agent that has set his price high and probably isn't in any hurry to sign with the first low bidder.
Barring injury, Kevin King will be on a roster come September. If the Packers youngsters aren't looking great or there is an injury, I would love to see King back in GB at the right price.
Far too many posters are holding that Tampa Bay game and the play at the end of the first half against King. Is he a Pro Bowl CB? No. Is he a decent depth guy and part time starter, yes.
I agree with your last statement. King is a decent depth guy. His problems aren't all of his own making. Yeah he made two critical errors in the NFCCG against Tampa. But so did Aaron Jones by fumbling on the first possession of the 2H. That loss was a team effort.
But because in fans' minds, TJ Watt was passed over for King, King has a lot more to live up to, and that's ********. First of all, no one knew how TJ Watt would play at the NFL level. If that we're known, he would have been picked in the top 5. King can't be blamed for that, but he is.
So overall, most fans have a dismal view of King. He needs a new start, a new environment where he doesn't have all this baggage following him. GB can always find depth at CB, so letting him go isn't a concern. And he'd be gone by now if anyone was interested.
My guess is that he starts the season unemployed. Or he may get picked up during TC if there are injuries. He'll play somewhere this year. It just won't be in GB.
