Murphy is so consistent. He can run 1:44 and 3:36/3:52-4 all day. This bodes well for the rounds. He also seems to handle traveling across the world really well.
Positive spin for a 5th place finish

Go back and look at the WC and Olympic finals, consistent 1:44 and 3:36 are the athletes who make the finals. Making finals favours athletes who are consistent versus one-off winners.
