First, let me say that I am British and don't really follow college running. Lex and Leo were obviously outstanding high school athletes but did anyone seriously expect top-20 performances from them as 18 year olds in 8k races against high quality competition? Very unfair to say they have "disappeared" as this is the second race they competed and scored at this season. Lex's time and finishing position would be considered respectable by most people, no? He was only a second behind Sprout who is 3 years older than him.
