It says something to his perceived talent and performance in college.
Also it speaks to his performance at the combine.
It is part of the resume when looking for another job.
The fact that he led a team to the Super Bowl speaks about his abilities.
He excelled in Harbaugh's scheme but not so much in Kelly's. Not every QB is right for every scheme.
But QB's of lesser talent were hired.
Anybody who knows anything about football knows that.
There was a time where he was perceived as being good.
That time ended.
Not in the minds of anyone who knows anything about the sport. There was near unanimous consensus among NFL analysts that he was more talented than many of the QBs who started for teams in each of the last 3 seasons, including several 2nd and 3rd string level QBs who got their staring jobs while Kaep was on the market. And not in the minds of the NFL legal team who would never have agreed to this very damaging settlement if there was a case to be made that Kaep was clearly no longer an NFL level QB.
Now that the NFL's hush money payout shows beyond reasonable doubt that their was evidence of collusion (and likely racism) among NFL owners that they wanted to hide, you are trying to rehash the already well refuted nonsense that he simply was not good enough to start in the NFL. The objective evidence (and the subjective evaluation of nearly every respected NFL expert) makes it clear that he was a far better choice for numerous teams than the person they hired, leaving just 3 possible reasons why he was not hired:
1) Every owner of a team that brought in a new QB during that time independently decided that they cared less about winning and therefore about profit, than they did about punishing this uppity negro who dared to complain about cops murdering blacks.
2) Every owner of a team that brought in a new QB during that time independently decided that the massively increased profits that inherently come with having a better team was not worth to potential loss in profit from their racist fans who might boycott the team b/c they hired an uppity negro who dared to complain about cops murdering blacks.
3) Those owners engaged in some level of coordinated effort (possibly with other owners who didn't hire a QB but wanted to protect the brand) to ensure no one hired him and provoked further boycotts by the leagues many racist fans.
BTW, the NFL's settlement and gag order that they demanded also proves that Kaep was never offered a contract for any reasonable amount of $. Because if they had, there would be record of that which would emerge in the depositions and make it a slam dunk easy and quick defense in court in the court of public opinion. This settlement which they already spent many millions and 18 months trying to fight cost the NFL tons in both $ and brand damage and precedent of future suits. They would have to be the most incompetent organization and lawyers imaginable to have done that to themselves, unless they knew there were facts the trial would make public that would cause them even more immediate and long term damage.
