Eras aren't defined by any particular length in baseball. You can still call this the era of Vladimir Guerrero Jr. and Bo Bichette, with the Blue Jays continuing to try to make good on the plans they laid nearly a decade ago to build around a young core. Before this came the era of José Bautista and the "bunch of renegades" who brought Toronto back to the postseason.
What's next, then? The Blue Jays could keep the good times rolling by extending Guerrero Jr., but at this point, it would need to offer the young star the world to keep him from testing free agency next winter at just age 26. Another big-name signing could extend this window, too, which the club has tried to do with Shohei Ohtani, Juan Soto and others, but it hasn't landed one yet, and George Springer's six-year, $150 million deal in January 2021 stands as the largest in franchise history.
