After his long run as the Chargers’ starting quarterback came to a fairly amicable end, Philip Rivers landed with the Indianapolis Colts on a one-year, $25 million deal.

The sudden retirement of Andrew Luck last August pushed Jacoby Brissett into the starting lineup for Indianapolis. The team started 5-2, as Brissett was among the league leaders in touchdown passes through Week 4, but his knee injury against the Steelers in Week 9 was a turning point. Brissett missed just one full game, but was clearly diminished trying to play through the injury. The Colts lost five of their last six games to finish 7-9.
