The last points the Pats scored in SB46 came with 11:20 left in Q3.In both of his Super Bowl losses Brady led the team on 4th quarter drives to give his teams a lead
That still doesn't make "getting there" an achievement in the context of the question. What counts is the performance in the Super Bowls, but that's not what you initially said.Those performances don't count against him in my eyes.
Looking at the performances, the offenses scored 14 and 17 points respectively in the two losses - obviously not all on Brady, but probably also not something to support an argument pro-Brady.
Looking at all their Super Bowl performances by something like ANY/A, Tom's best performances are just slightly better than Montana's worst. (Source)
Tom is the GOAT, but I don't really see how an argument can be made for him over Montana for Super Bowl QB.
