That's a whole lot of if's and maybe's. I could add more on top. Indeed, I specified that I expected the relationship between OL and QB might have to be analysed on a team by team basis. I don't assume all QB's to be the same or affected by OL play in the same way. I said it's common sense that OL play will have some effect on QB okay. I didn't say what our how much. I just said that was a starting point for investigation, and investigation at a particular level. Do you have anything concrete to add about this 'uncommon' sense?
You could certainly do that. Simply determine whether QB performance varies as a function of offensive line measures on a game-by-game basis, for an individual team.
