Jacoby Brissett played pretty well when he was called upon in 2017. He was not the reason the Colts finished with the third worst record in the league. He actually almost had a 2:1 touchdown to interception ratio that year, and that was without having a training camp with the team.
But now that Andrew Luck is completely healthy, Brissett seems destined for backup duty as long as he is in Indianapolis. This is the second straight offseason that teams have inquired about his availability, and the second time the Colts have shut down talk.
