It appears when a player is knocked out he automatically rolls over. It would be cool if the ragdoll would remain exactly as it is so a dead player would look the same as a knocked out player, that would help with confusing the attacker on whether the target is dead or not.
for example I have seen players ragdoll from a crouching position then leaning against a wall next to them when dead. It would be cool if knocked out players would remain in the same position until they wake up.
