Anyway, back to the fun. Let's pick random Marino/Rivers seasons exactly 20 years apart.
Marino - 1988 - 27 years old
354-606 (58.4%) ... 4,434 yards ... 28 TD, 23 INT
Rivers - 2008 - 27 years old
312-478 (65.3%) ... 4,009 yards ... 34 TD, 11 INT
So Marino gets extra credit for throwing the ball more than anyone else in 1988? And Rivers gets downgraded because he threw it as much as any other team in the league in 2008? Forget the fact that there are skilled DBs all over the field on passing downs in this era while Marino had his 3rd WR being covered by a safety.
It's easy to throw around insults then run away. But I'd rather someone maturely explain why Marino's passing stats are somehow more important than Rivers'. "Marino played in a running era" is not a valid answer. So we'll upgrade all of Adrian Peterson's stats because he plays in a passing era?
I want to make one thing clear, though. Dan Marino is the best QB I've ever seen.
But this "we can't compare eras" argument is tired.
I think what you are missing is that the actual numbers in each year comparing eras are less significant than the annual RANKINGS in comparing players.Looking at Top 5 finishes in the following categories:
completions, completion%, passing yds, passing TD, YPA, passer rating
Rivers
completions - 2
completion% - 1
passing yds - 2
passing TD - 2
YPA - 3
passer rating - 3
TOTAL: 13 times in 6 seasons as a starter (but 8 seasons total)
Marino
completions - 12
completion% - 5
passing yds - 11
passing TD - 8
YPA - 4
passer rating - 6
TOTAL: 46 times in 17 seasons (with one and a half years total time lost due to injury)
Rivers has been more efficient that Marino was, and if Rivers were to keep playing at a high level for another 9 seasons he might have a lot more Top 5 rankings. Similarly, maybe if the Chargers passed more he might have higher rankings, too, but it's not like the Chargers have been a run first and run some more type of team.
IMO, that's a better way to compare players in different era than just looking at the raw numbers.
As for the Romo / Rivers comparison, I think it's funny that Romo gets written up for not having won anything, yet Rivers gets a pass and is the one that is irreplaceable. Given that in most years the AFC West has stuggled to field teams with winning records (KC was the only 10 win team in the division besides the Chargers in the Rivers era and accomplished that one time), the Chargers should have been set up to make the playoffs every season. But the past two years they didn't make it when the division was soft as ever.
