You're right...but you're someone with clear passion and knowledge about the QB position. If the rankings aren't capturing something important, I think it's important to investigate it and at least try to make it adjustable.
With Marino, I do hope/suspect that a lack of peak score that's a big part of why he's not moving up despite any type of adjustment attempts; I think it's something that we know intuitively about him, that he was so great in the mid-80s, there should be some mechanism to account for that. This is why I like getting your feedback. Feel free to rant and rave all you want...all points are good points beause we need all the perspectives we can get. And I like doing this; I'm looking to keep building this and expanding its options rather than closing up shop and sending out some finalized list.
With Marino/Elway, I get what you're saying about why there should be some way to rank them over "the very good but not historically great Big 3" of Rodgers, Brees, and Favre, other than just saying "okay, I'm just going subjective here." I sent you a response last night, and then I woke up today, did some other things, and it clicked that peak score might be what was missing there. That's the thing: there are probably actual data points that support what you're pointing out here, and what others are pointing out...they may be hard to find and aren't showing up with the more traditional input data I've been using, but there's probably something that I'm missing. I want to have a system that's efficient and as simple as possible but accuracy is the most important factor and that sometimes means more complexity.
What I'd love to have in the end is not some end-all, be-all list, but some fairly intuitive adjustments that allow you to fine tune the rankings. And if we can solve the Marino problem, we're likely going to have solved a lot of other problems as well, as we'll have the ability to adjust those out too.
There are other other guys on the list whose peaks are being undervalued, so this option should exist; it's another way to likely water down Eli; another way to likely bridge the gap between Staubach/Young and Manning; and it's a way to leapfrog players who just don't excite you...someone like Roethlisberger or to some degree Brees. Someone's peak play is often the very reason we started getting excited about the NFL to begin with...much like a Tiger Woods or Michael Jordan effect; it's important for the sport itself.
