His training was not OK before EC, but certainly he did not think it was so bad that he lost even his triple jumps. Under such circumstances, you are right about pulling out because he has no chance to medal, but that is based on his body cannot take it to finish LP. Maybe in your eyes, could not perform LP is the same as "seeing no hope to medal, therefore pulling out of competition" are the same thing, but they gave people completely different message. The former means he has to pulled out because he is too injured to compete, the latter means he is coward not evening want to fight.
My English is not good, so I hope you understand what I want to express.
