I like the idea of Raih as the QB coach, maybe groom him to be next OC if Brian Ferentz takes over for Kirk in a couple of years.
If WR spot opens up, maybe reach out to some young former Hawks in the area (Martin-Manley, McNutt, Hinkle). All three are coaching/working high high school players currently. Maybe helps continue the much needed youth movement.
Last spot depends on who you could get. What about Bobby Diaco? Not sure if he'd go from Uconn head coach to position coach, but maybe offer him D-line & Asst. HC title. Maybe he'd be up for a couple year stint at his alma mater. Then Morgan could move back to O-line.
