8. Philip Rivers
Rivers left the Los Angeles Chargers for the Indianapolis Colts after 16 years of service. The 38-year-old is perhaps the least-vaunted of the golden generation of elite veteran quarterbacks but has a cannon of an arm. Furthermore, he made the Pro Bowl eight times in his career.
But there is no doubt that his level has dropped. Rivers was awful in his last season for the Chargers. Of course, he didn’t have much protection or the greatest weapons, but it still felt like the right time for them to cut ties with him. Now he has to prove that his decline isn’t insurmountable with the Colts.
