The 16 game schedule makes no difference. The record is not based on actual time like Golf records for example but actual regular season starts. Regardless of 14 starts or 16 starts a season it still only took Brady 131 starts period to reach 100 wins, the number of years it took him is not part of the calculation and is not a factor. The only QB on the list who played during the 14 game season era was Terry Bradshaw anyway. Montana came up in 1979 when the NFL had already changed from a 14 game schedule to a 16 game schedule during the 1978 season..
It took Bradshaw 11 years to reach his 100th win. Brady (counting 2008 when he only started one game due to his knee injury) is now in his 11th year but if you throw out his rookie year 2000 when he made no starts and had no wins and also the one start 08 season he accomplished his 100 wins in 8 full seasons and one fourth of the current season. That is a totally different method of counting how fast a QB reached 100 wins and not what they are talking about here.
The record is based on wins within a given amount of starts not how fast in years played it took him to reach 100 wins.
The method this record uses is number of wins vs games started. Brady did it in 131 starts while Montana needed 139 starts. The time involved had no effect on the record. Theoretically a QB could take 20 years if he spent 10 years as a back-up before he got his shot and become the fastest QB to win 100 games if he had no starts during his back-up years.
Bradshaw had zero no win seasons, his worst was his rookie year when he made 8 starts and won 3 of them. He only won 107 games total in his career. Brady will pass that number this year, which is another record altogether.
Brett Farve has the record for most wins by a QB with 181 wins but it took him 285 starts to do it. Since the super bowl era Farve holds the record for most wins 181 and most losses with 104 since 1966.
All time Fran Tarkenton has the most losses with 109 in 239 starts (including 5 ties). Tark got off to a brutal start after his first three seasons with Minnesota then an expansion team, he was 8-27-2.
