Coaches don't miss 32 yard field goals and take sacks on 4th down. Rhoads might be done but this is 100% on the players.
Smart coaches who intend on going for a FG to win the game don't run a play prior to kicking the FG making the kicker have to kick from an awkward angle. And even if Netten wanted it there, have Richardson drift over to the hash and take the knee. Don't have your running back break tackle after tackle over on the hash, risking fumble after fumble.
Did CPR miss the kick? No. But he absolutely mismanged the situation about as badly as you can.
