The part i think you are missing that maybe i didnt make very well is the system makes the qb as much as the QB makes the system. Its not a conversation about unicorns as much as it is chickens and eggs - maybe not that exactly... just that you dont have one without the other.
Stafford was a nothing more than a nice talent before McVay.
Purdy... i doubt his game translates well outsude of SF. He has shown to not be remotely the same player when his line plays badly. He had a stretch this year where he led the league in INTs when his protection sucked.
Goff was cast aside and traded for marbles.
Darnold is now being talked about as the best Goff.
Steve Young was Matt Stafford before he landed in SF
Doug Williams was in the same purgatory as Steve until he got to Washington.
Has Russ been elite since he left Seattle?
Would Bo Nix being doing what he is if he was in Seattle?
This whole debate could just stop at Sam Darnold this year. Like Smith, he was left on the scrap heap, wasnt even supposed to be a starter, and now he is among the league's best and he has a far better supporting cast than Geno.
Arguably one of the best 3 or 4 qbs of all time in Arron Rodgers has 1 SB to his name.
Over the last 10 years, if you take Mahomes and Brady out of the picture the other SB winners were qb'd by guys who were 'reborn' in new systems with better coaches.
Stafford after Detroit
Nick Foles after failing in a few spots.
Peyton Manning in his old age (he rode that team to a SB)
Russell Wilson (doesnt qualify as reborn but he didnt carry the team) well before he was 'the guy'
And Eli Manning (also didnt carry his team), who is the poster boy for non-elite, but still champion.
Andy Reid has groomed QBs at every stop, taking McNab to great heights, Vick, and now Mahomes.
The Patriots had a system of developing a team that was so good it was coined the 'Patriot Way'.
And when Brady left NE, he hand picked TB because of how brilliant an offensive mind Bruce Arians was.
I will say it again. Saying what Geno cant do under better circumstances is as foolish as stating defintively what Goff would do over the rest of his career after he was traded to Detroit.
Or what Stafford would do.
Or Darnold now.
Give him a competent system and lets see how high he goes.
Great to see that folks outside the PNW dont view him as harshly as his own Russ hardened fans do.
