Philip Rivers signed just a one-year deal to play with the Colts. While that deal can easily be extended at the end of 2020, that doesn’t give Rivers a whole lot of security. It means he needs to play well immediately to still have a future with the organization.
Not all of it is on Rivers though. A lot of it is on the coaching staff. They have to create gameplans that best utilize the skills that he possesses. Doing that will put him in the best chance to succeed and in turn, give the team the best chance to succeed.
