Out of the hundreds of QBs that have played in the league during the decades you just covered you just named 8 guys. Three or four of whom weren’t starting regularly late in their careers and certainly not for their original teams. I don’t think we are going to see multitudes of guys playing that long.
I just looked it up and there were lots of guys back in the day... then it tapered off...
but it looks like it is making a comeback
didnt realize george Blanda played until he was 48...damn...
here are the guuys who played at 40... others were higher...
