RENTON, Wash. (AP) — Seahawks coach Pete Carroll is expressing regret for not signing Colin Kaepernick when given the opportunity. Seattle brought Kaepernick in for a workout during the 2017 offseason and had another visit a year later canceled. At that time, Carroll said Seattle chose not to bring Kaepernick aboard because Carroll viewed Kaepernick as a starter, not a backup. In hindsight, he says he wishes he would have given Kaepernick a shot even if it meant a potentially awkward role as Russell Wilson’s backup.
