It's an extra special problem because today's game is geared way more toward the QB than it's ever been before. If you don't have one that can play worth a damn, your chances of success as a team go down.
Yeah, you had QBs like the ones you mentioned from yesteryear that didn't amount to much, just like you do now, but the success of your team wasn't almost solely dependent on your QB play then. I mean, you've got HOF QBs from the 70s with nearly as many INTs as they do TDs.
Terry Bradshaw for example, had 17 TD and 23 INT the 2 years the Steelers won their 1st 2 SBs. 26 TD, 25 INT for the 4th SB year. 51.9 career completion percentage, 212 TD, 210 INT. Was he really worth a flip behind center? Bartkowski had better numbers than that, yet Bradshaw's the HOFer.
The ratio of bad QBs may be the same as the 70s, but now the game is so QB friendly that you can't survive with those Bradshaw, Bartkowski type numbers. So much of your success today lies so heavily on the QB.
So with a league that has turned so QB friendly I just think it would be in their best interest to have competent QBs in their league. Today's QBs aren't learning the NFL game in college and teams have very little patience with them learning on the fly. So a developmental or instructional league would be a huge benefit, IMO.
