See, but this is exactly the sort of thing I mean. I don’t see a single way in which Joe Montana is clearly better than Brady. Statistically, Montana and Brady are virtually identical (except that Brady, having thrown about 2000 more passes than Montana in the same number of seasons, has significantly greater counting stats). But completion percentage, TD%, INT%, Yards per attempt and per completion… all are so close that the difference is statistically insignificant.
Not so much a stats guy? Well, Montana made his reputation on 4th quarter comebacks, and indeed he’s credited with 31 in 15 seasons, plus 5 in the playoffs. In his own 15 seasons, Brady has 35, plus six in the playoffs.
Montana’s career winning percentage was .713 as a starter; Brady’s is .773 (Brady has a similarly better winning percentage in the playoffs, too).
Both guys have four Super Bowl rings, including three MVPs. Both guys had extremely memorable fourth quarter comebacks to steal victories in a Super Bowl.
Montana played for one of the best head coaches of his generation; so did Brady.
Both guys throw were/are known as cerebral QBs who make excellent reads, avoid catastrophic mistakes, and use short timing patterns to maximum advantage.
As far as I can tell, based on any measure you choose - statistical, anecdotal, results-oriented - Joe Montana and Tom Brady were basically the same quarterback through 15 seasons. I’d look with suspicion on anyone claiming that either of those guys is obviously better than the other, and am perfectly happy to say that they’re both part of the absolute upper-tier elite. Which one was better? I don’t know, I’ll never know, and I don’t care; I’m just glad I saw both of them play (and glad I saw my team beat both of them).
