When Lance McCullers Jr. agreed to an extension with the Houston Astros on Wednesday, two things happened.
The first thing is that McCullers signing in Houston long-term removed one of the Mets' best options to potentially replace Noah Syndergaard via free agency after the 2021 season.
The second thing is that McCullers' deal with Houston possibly provided a roadmap of sorts that the Mets can use to extend Syndergaard.
McCullers, 27, agreed to an extension worth $85 million over five years that will start with the 2022 season, per multiple reports.
The five-year deal locks McCullers up through his age-32 season.
While Syndergaard has more upside than McCullers, he is a year older and is coming off Tommy John surgery (whereas McCullers already successfully returned from the procedure in 2020 after missing all of 2019).
So while Syndergaard might aim for more money than McCullers received and likely deserves more, there's a case to be made for using McCullers' deal as a baseline.
Let's look at what Syndergaard and McCullers have done so far in their respective careers...
SYNDERGAARD
3.31 ERA (2.92 FIP) and 1.16 WHIP while striking out 775 batters (9.7 per 9) in 716 innings (118 starts, one relief appearance) over five seasons.
McCULLERS
3.70 ERA (3.29 FIP) and 1.26 WHIP while striking out 565 batters (10.0 per 9) in 508.2 innings (91 starts, three relief appearances) over five seasons.

A key separator between Syndergaard and McCullers is that McCullers has eclipsed 128 innings just once in his career and has never reached 150 innings.
Syndergaard, despite an "injury prone" narrative that tails him for some reason, has eclipsed 150 innings four times, including a career-high 197.2 in 2019.
He also has better stuff than McCullers (and one of the best fastball/slider combos in all of baseball).
