It's not about "marginalizing our past" ... it's about putting it into proper perspective, in light of criticisms of the present.
You are romanticizing the JoePa era. And being unduly harsh on the present.
In the last 25 years of JoePa's tenure (1987-2011), 12 of those were 4-loss or worse seasons. 18 of them were 3-loss or worse seasons. Only 2 of them were 0 or 1 loss. So when we see the threads about Franklin having a ceiling of a 2-loss team ... Dude, in JoePa's last 25 years, only 2 of those 25 teams were better than that (a 2-loss team).
So, just imagine Franklin is here for 23 years, and he posts the following: 1 9-loss year, 2 7-loss years, 3 6-loss years, 1 5-loss year, 5 4-loss years, 6 3-loss years, and 5 2-loss years ...
How would you characterize his tenure?
Is that "elite," and you worship him, and wish our next coach could get back to that?
Because that's what JoePa did in 23 of his last 25 years. Adding in his amazing 1994 undefeated team (17 years before he finally left), and the 1-loss year ... that suddenly turns that 23 years of performance into 25 years of being "elite"?
Take that 2008 team ... great season. Fun. But if it happened now ... you and other Franklin critics would be pointing out that we were lucky to face a 3-9 Michigan team, and that we had a bye week before Iowa (a team that would have been 7-5 in the regular season had we beaten them), and still couldn't pull off the win ... because of bad coaching decisions, no doubt ... and when we finally went up against a top team in the bowl, we saw that we were inevitably not up to their level. Sadly, that would be the narrative pushed by those who constantly look for the negative in Franklin-coached squads (of which there are many on this board).
