Centro see's Steph.. goes up to him "Hey man cool to meet you" they talk.. "I actually won a gold medal in track this year at rio"
Same as the first, but Curry is a nice guy and eventually asks "So what do you do"? In which Centro would reply "Well I'm a professional track athlete" and the conversation eventually leads to him saying he won a gold.
NOT AS LIKELY
Someone comes up to Curry and points out to him "Yo, that guy was a gold medalist in Rio, in which Curry, being the nice guy he is goes up and introduces himself.
DEF NOT LIKELY (But what Centro would like us to think)
Curry recognizes Centro from the 1500 final in Rio and fanboys him saying "Hey Centro! You know me, right"?
Would love to hear some other possible scenarios. Fire away, LR.
