i dont have a quantitative assessment of this and im not sure you can but anecdotally i feel the oline has some issues and it is linked to the inability to go deep this year. to me the offense ran fine as long as we were in manageable down and distances. and they did that for the most part which is why the rank is high. but when they got a penalty or a sack and had to play behind the chains, the oline could not protect goff long enough to push the ball downfield (as evidenced in the final drive of the gb game). personally i think mcvay knew this and protected the line with the run and the short passing game. in order for goff to be effective imo he needs protection (like brady). i dont see goff going anywhere so id like to see some more investment on the oline this offseason. i think center may be my #1 priority.
