Those teams you listed are about it.
There are enough solid QBs out there.
Look at what has happened to Jared Goff he has an actual coach now not Jeff Fisher and McVey is developing him.
The Jets are tanking.
The Browns have Kizer.
The 49ers are clearly rebuilding this year and will get a QB in the next draft.
Andy Dalton has taken his team to the playoffs 4 of 5 years that isn't a bad QB. He has sucked in 2 games though.
QBs are better than you think:
The entire NFC East, South have solid QBs.
Detroit, Green Bay have solid QBs.
Chicago has a rookie and Glennon.
Minnesota has Bradford
Seattle, Arizona are fine.
San Fran doesn't have a QB.
Rams have a young QB.
The Patriots have 2 QBs Brady and Garrapolo.
The rest of the AFC East blows.
Big Ben, Flacco, Dalton solid.
Mariota, Luck are solid.
Jacksonville doesn't have a QB
Houston has a rookie.
AFC west has 4 solid QBs. Rivers, Siemon, Carr, Smith.
By my count 6 teams don't have solid starting QBs and if you count Jay Cutler then it's 5.
