While I don't entirely agree with you, you made the case for how you see it and why.
And that's all I was soliciting....I want to see what some of you think about the place of a RB, especially Gurley, as an important cog (or not) to win a Superbowl.
And there's a lot of truth to what you point out especially when you say that given a HOF QB and HOF HC, those two factors may be the most influential of them all.
And, you are right that as of today, we don't have an HOF QB or HC. Yet. That determination can only be made with time. You seem to indicate that you don't believe Goff will ever be HOF. I'm more willing to give it the benefit of the doubt that in time he might become one. Ditto with McVay. But for both you and I, at this point in their young careers, it's just speculation and opinion.
So, again, well done. Lot's to think about.
