From Gemini:
Examples of successful quarterbacks who signed major extensions after their third year include:
Patrick Mahomes: Signed a then-record 10-year, $503 million extension with the Chiefs after his third season (his second as a full-time starter).
Josh Allen: Received a significant extension with the Bills after his third season.
Joe Burrow & Justin Herbert: Both were eligible for extensions after their third year and signed large deals with the Bengals and Chargers, respectively.
Brock Purdy: Though a late-round pick and not subject to the same rookie wage scale rules as a first-rounder, his unique situation led to a massive extension after he became eligible.
Sounds like a 2027 problem.
