I'll agree that Derrick had no shot of winning today. At best, we can speculate that he might have been able to beat Puskedra. But you could say the same of Riley, Mecheso and German.
However, the whole point of your post is ridiculously off, and based on an assumption that may be completely incorrect.
Chris Derrick and his coach knew afte 3km that they were basically out of the team title as they weren't even in the top 5 team wise and had over 250 pts at 3km.
How do we really know this? Sure, I'm sure his coach knew, but we don't know that Derrick did. It's a loud race, there's lots of shouting, and at the point where the announcers are reading off team scores, the athletes generally aren't near the loudspeakers. It's possible his coach could have shouted or hand signaled to him, but also possible that he couldn't get a signal through. I'm not saying that Derrick didn't know that, but we can't say that he did, and if you think it through, it could go either way. The only thing we know that he knew is that Heath wasn't right next to him.
Besides that, even if your assumption is correct, you made an awfully harsh judgment there. The guy went in to race for the team, and though he looked like he was jogging the first 5k, from about 7k on, he was all out. He has fire, he has drive, and with the exception of this meet the past two years, and maybe doubling NXN and FL his senior year of HS, he has rarely compromised his chance at going for it individually for the sake of the team. Seems to be an all around quality guy and if he's healthy in the spring, we'll see him chase some fast time and individual glory.
