Matt Ryan
Many rival fans felt a sense of schadenfreude after Andrew Luck retired. The Colts went from NFL icon Peyton Manning to a brilliant replacement in Luck. However, he quit the sport earlier than anybody expected. Indy desperately scrambled to replace him with short-term stopgap options including Philip Rivers and Carson Wentz.

Finally, in 2022, they signed Atlanta’s long-tenured quarterback Ryan. The former MVP was one of the best NFL quarterbacks of his era. But he struggled to adapt to a new system and had the worst season of his career. The Colts signed him because of his experience, but in the end, it was a disaster (via ESPN).
