Louisville took its first steps in replacing Greg Brown and Terrell Buckley by hiring former USC defensive backs coach Keith Heyward today. Heyward is the first new coaching staff hire for Bobby Petrino since his return to Louisville for the 2014 season. Heyward's exact duties have not been officially spelled out yet, but he's reportedly joining the Louisville staff as defensive backs coach. With Brown and Buckley, the cornerbacks and safeties were coached separately. If that will continue or if Petrino intends to put them under one coach and hire a coach for a new role remains to be seen.
