The Toronto Blue Jays' signing of Dylan Cease shouldn't have much impact on anyone else in the rotation, save for perhaps José Berríos and his long-term contract. Cease is a true ace who doesn't overlap with anyone, even Kevin Gausman.
The same can't exactly be said for Cody Ponce, whom the Blue Jays signed to a three-year deal shortly after locking up Cease. Those two, alongside Gausman, Shane Bieber, and Trey Yesavage, should round out the team's rotation on Opening Day.
That's a mighty impressive starting five, especially if Berríos is retained as competition for Ponce (or if Ponce is used as a swingman out of the bullpen).
