Everyone likes Coach Kueck (me included) but most, outside QB's, haven't sepnt much time around him to become too attached. I say if Kueck stays on staff it won;t be too big of deal for players.
Synder is a Marshall guy and has a nat'l champ ring so there will be a level of instant respect. I imagine it would be tough on some players if their respective position coach is not being retained though.
Maybe Herd48 has some thoughts on this
