No Im saying there are guys every year who fall the cracks of the incompetent management of the various franchises that can legitimately play. The franchises play the players they have the most money invested in and not always the best players.
There are those franchises who have traditions of poor rosters, poor draft execution, etc. Do I think you could find some off roster 4-6 year guys to help bolster a depleted roster lower-tier NFL team, yes.
Mac Jones is one of the 32 best QBs in the NFL but he may not find the right job opening with the right franchise. I would argue that AJ would have been every bit as good as Tannehill on the Titans with Derrick Henry as it's primary offensive weapon. There is nothing special about Ryan Tannehill, Andy Dalton, Ryan Fitzpatrick, etc. For good sakes, Tyrod Taylor is still getting live snaps in the NFL. There are certain players still in the league thst defy logic...
