Kyle Gibson has been good but doesn't need to be resigned
Between Lance Lynn and Kyle Gibson, the two veteran starters signed to bring stability to the Cardinals rotation, Gibson has certainly been better. While Lynn boasts a lower ERA, his spotty availability while not providing the necessary innings and weaker peripherals make Kyle Gibson by far the better of the two. Gibson has also stabilized a shaky Cardinals clubhouse. In an ideal world, the Cardinals would be able to bring back Gibson, but their glut of mid-tier veteran pitching means he's a bit of a redundancy on the roster.
For the 2025 season, the Cardinals have Sonny Gray, Steven Matz, Miles Mikolas, and Erick Fedde under guaranteed contracts. With Andre Pallante all but having a rotation spot secured for next season, the Cardinals don't need another expensive starter with little upside. St. Louis needs to find and develop young, cost-controlled arms, and bringing back Gibson for 2025 would only be a detriment to that goal. Of course, the Cardinals will have pitching injuries, but having five starters under veteran contracts would not be a wise use of resources.
Michael McGreevy certainly deserves a look after his fantastic spot start while other names such as Gordon Graceffo, Adam Kloffenstein, and Sem Robberse should get chances as well. Quinn Mathews will also likely get chances to start later in the season. And while Gibson is a preferable name over Mikolas or Matz, the Cardinals don't have a choice to let either of the other two starters go with a club option. Trading either or both may be the best decision, but it's unlikely the organization will be able to offload these disappointing contracts.
Gibson has been great in his first season as a Cardinal, but unfortunately, it may have to be his last season as well. Unless St. Louis can find a way to creatively move other contracts, Gibson has no real place on a roster that should prioritize the future.
