Drew Brees
Brees made some big history during the 2019 season and proved he’s still an above-average passer even though he just turned 41 years old. It’s likely that Brees returns to the Saints this offseason, but the NFL is unpredictable at times.
If Brees does become available, he would be one of the few free agents the Colts should consider signing. Having two quarterbacks on relatively big contracts isn’t great for the future, but the Colts have the money to pull something like that off for the short term.
No one is really expecting Brees to leave but if he does, the Colts would be an interesting destination.
