I'm not sure what your point is? The fact that Watson and Allen are 1 and 2 suggests that mobile quarterbacks take the most sacks. Mariota just took 11 and it certainly wasn't all on the OL.
The only way to consistently make your OL look better than it is, is to get the ball out quickly. Dak and other scramblers don't do that.
Watson and Allen are very young. Being athletic has zero to with them taking sacks.
Having DC's blitz and/or take away their first option is what causes most of it.
Getting the ball out is fine and good until it's 3rd down and you throw a 4 yard pass when you need 8.
Then you are an idiot.
Josh Allen isn't a running QB per se. He is a reasonably athletic guy that is scaring zero people with his legs.
Eli Manning is the definition of pocket passer and he is a veteran and he is 2nd.
Watson's best game of the year was versus us and he had his most rushing attempts with 10 and also took only 1 sack.
We had to spy him with Jaylon which reduced the pass rush by 1 person in many cases.
The next week Watson didn't rush after we beat him up and he had 2 attempts for 2 yards but allowed 7 sacks.
The one thing you have to give PFF is they do credit sacks to the QB if they hold it too long. It's far less critical of OLs than just sacks allowed.
HOU and BUF have poor OLs by any account.
