I wonder why people keep repeating this? From 2000-2021 (I can count this year since neither QB this year is on a rookie contract), the SB winning QB is on a rookie contract 31.8% (7 of 22) of the time. The SB losing QB is on a rookie contract 22.7% (5 of 22) of the time (or 27.3% combined). 6 of the 7 SB winning QBs are probably future HOF QBs (Brady 2x, Rothlisberger, Wilson, E Manning, Mahomes) with Flacco as the other. Of the 5 SB losing QBs, you have Wilson as future HOF probable with McNair, Grossman, Kapernick, and Goff. Best way to win a SB is to have a HOF level QB on a rookie contract. The second best way is to have a HOF level QB. Last year you had the Chiefs with Mahomes, that's one Year before you had Patriots with Brady (see the rest of my post) Year before you had Eagles (although the backup QB actually played in the playoffs, if anything, strengthens my point) Year before you had Patriots with Brady Year before you had Broncos with Manning on his last legs making less than he did earlier in his career and likely hurting more than helping that team to a super bowl run (This one's kind of an outlier but doesn't really point to good QB play leading to a title) Year before was Patriots with Brady Year before was Seattle with rookie contract Wilson (has not won a super bowl since) Year before was Ravens with Flacco (Before he got big payday, never won another after) Year before was Giants with Eli (First legitimate outlier, they were 9-7 though so maybe chalk it up to luck) Year before was Packers with Rodgers before he got paid (And also many forget, due to the labor situation at the time, this was an uncapped year, so I probably shouldn't even count this one) Once you go back much further before this, top draft picks were more of a burden than help with the crazy rookie contracts given out
