Corbin can be the poster boy for Flags Fly Forever. He won Game 7 of the 2019 World Series. That was the first year of his massive 6-year contract with the Nationals. He's been bad ever since. Do they regret his contract? Well, flags fly forever and Washington had a pretty big Big Three in their rotation that year.
And yet, somehow, despite his rapid decline he's started 30+ games every year, except only 11 in Covid-shortened 2020. He's also a poster boy for Innings Eater.
