I can't post it because it's a paid subscription. But, it you can access it somehow, it is perhaps the best, most thorough and fair evaluation of NFL QBs I've seen in a while.
It is based on the votes and explanations of 50 NFL Execs and Coaches. So, it has some weight and isn't just sports writers opinions. Some it is is pretty obvious; others a bit surprising.
They divide them into tiers 1-5.
At the top is Mahommes and Stafford, with Burrow and Allen right there with them.
Then the drop off begins. Some notable names: Goff at tier 2. Purdy mid-tier 2. Mayfield lower part of tier 2. Aaron Rogers firmly in tier 3. Kyler Murray a tier 3 with many thinking he is a tier 4.
Some ot the later tier 3, and then 4 and 5 guys, are young and just haven't yet earned higher ratings although they clearly have the potential. Some of the tier 4 and 5 guys have been overrated for a long time (Smith and Brissett for example) and really are nothing more than solid back-ups but schemed into playing well enough to survive as starters.
