As has happened with numerous teams with quarterback injuries this year, many fans were quick to speculate that Colin Kaepernick might be a suitable candidate to join the Birds before their playoff push. While Kap's return to the league is unlikely, he's a unique fit for the Eagles needs in that he is a mobile quarterback that has experience in big games. After Carson Wentz's season officially ended due to a torn ACL, Philadelphia sports fans began to speculate on ways to save their promising season, and one name has come up in multiple circles of water cooler conversation: Colin Kaepernick. Kaepernick has been out of the league since asking for his release from his contract with the San Francisco 49ers last season.
