OC probably got some say on who he wanted to keep around to help with the offense.
Kostich isn't a surprise, despite some opinions, he's a good ST coordinator and is well liked by players, parents and high school coaches, plus has a ton of connections. Adding nickelbacks to his plate will take that off of Stepps, who will just handle CB's.
Still need a safeties coach in the secondary, plus Edge, LB's and DL.
