@StuartF What about
"John entered college. He studies hard for a few years. He will not, however, get a job at the bank as he hopes to. After the graduation, John made a career in politics".

you can use the narrative present: "John enters college. He studies hard for a few years. He does not get a job at the bank. Instead, after graduation he makes a career in politics."

"You will have been quite athletic" = "I suppose you were quite athletic". In your 'John' example, there is no supposition, just a statement of what happened.
