I only disagree on Point #1, especially when it comes to the Packers.
I think we all know that if #12 goes down, game over, season probably over too. Kizer seems to have established himself as the #2 and that isn't saying much IMO. I would rather see the Packers cut Boyle and Wilkins and put one of them on the PS, since I doubt both, if even either, gets picked up. IMO that roster spot is better served by using it on another position or player you know you can't slide to the PS. Taysom Hill might look like a bad cut a few years back, but the Packers were not using him like the Saints have, so that was the only mistake, not seeing his other talents. But holding on to him or Callahan at the time wasn't that important in the grand scheme of the QB position for the Packers. Word at the time was that they wanted to get Hill to the PS, but obviously that backfired.
Now if the Packers draft a QB high in the next few years, then I can see holding onto Kizer and that draft pick.
The only way I see the Packers keeping Boyle on the 53 is if they really see some great potential in him, but to me he looks a lot like the "Callahan's" that have paraded through Green Bay over the years, nothing special, just a camp arm with the hope that he will someday develop.
