You are missing the point. Yared doesn't owe Engles a phone call telling him to get ready. Engles had 2 years to get ready and blew his chance at the trails. I would do the same thing Yared did if I got hurt. Keep it on the down low and rehab like hell until the day of the race and make a decision after warm up. Craig isn't owed anything, he had the same chance to be there that anyone in the United States did.
Also, Engels would've s!@# the bed anyway. He said on the BarStool podcast that he's just been partying since the Olympics trials and wouldn't have been prepared to run.
