Tom Brady had 46 comeback victories in the 4th quarter (all time career leader). Patrick Mahomes has had 5 this year. Jared Goff has 4 this year.
Maybe you should beat a different drum.
It’s primarily a marker of longevity, (Career leaders are Brady, Manning, Brees, Roethlisberger, Stafford…), and a byproduct of being successful.
Successful quarterbacks will play in more games, and thus amass more of these drives, but amassing them over a short time frame doesn’t necessarily indicate that one is a good quarterback.
On a “per number of games played” basis, Geno has about twice as many as Brady. Is he about twice as good?
It’s a down year for Mahomes and the Chiefs. He is 45th overall for total career game winning drives. Goff is 62nd. Geno is 79th. Derek Carr is 13th. Kerry Collins 22nd, Jake Plummer 23rd, Tony Romo 25th.
