The other Quarterbacks (and the year(s) they lead the league)
Arnie Herber (1932, 1934, 1936)
Cecil Isabelle (1941, 1942)
Irv Comp (1944)
Tobin Rote (1956)
Lynn Dickey (1983)
Don Majkowski (1989)
Brett Favre (1995, 1998)
Of course Rodgers still has a chance to lead the league in passing yards, but he's never been within 500 yards of the leader so it seems unlikely he'd ever do it
I apologize if this is supposed to be an "offseason post" but I found it interesting enough to post
Source. Mahomes was the previous leader but yesterday's 52.3 rating dropped him behind Rodgers and he's now in 5th place with 100.4
Edit: "Accounting for 48 seasons" is misleading. There are three years of overlap between Favre and Rodgers on the same roster. All three of them technically account for 45 years of Packers history.
Mahomes' rating tonight of 52.3 dropped his career playoff rating from 109.8 to 100.4 (back behind Rodgers now, too!). Starr's career playoff rating is at 104.8.
I wish it could have been at the hands of the Packers, but I'll take it.
