In 2019, Garoppolo completed 69.1% of his passes, threw for just 3,978 yards, and tossed 27 touchdowns and 13 interceptions.
On the other side, Prescott was a little worse in completion percentage, completing 65.1% of his passes. But, he also threw for 4,902 yards and had 30 touchdown passes and only 11 interceptions. When you dive a little deeper in the numbers you'll see that Prescott had two fewer giveaways than Garoppolo despite throwing 120 more passes than the 49ers signal-caller.
Additionally, Prescott finished fourth in the NFL in Quarterback Rating (70.2) behind Lamar Jackson, Patrick Mahomes and Drew Brees, while Garoppolo finished 12th among QBs in QBR (58.8).
It's understandable that quarterbacks could get a little bump in the rankings after their team makes the Super Bowl, but it's obvious the players aren't paying close attention to the games or the stats when they vote on this list every season.
A positive in all of this is the fact that Prescott didn't even appear on last year's list, so this is quite the rise for the Cowboys quarterback.
Of the players who have made the top-100 list so far, Prescott was ranked higher than Kirk Cousins, Ryan Tannehill, Josh Allen, and Kyler Murray.
