There are just some events in life that are accompanied by a small but regular occurrence that would make us say ‘ah, it wouldn’t be X without X.’
An example that springs to mind off the bat would be ‘it wouldn’t be a Tottenham Hotspur season without inexplicably losing 0-3 at home to a bottom-half team’ (such is life as a Spurs fan). You get the general idea — there are happenings that accompany an event that help make that event what it is, even in a small capacity.
It wouldn’t be the NBA Draft without an international prospect from the ever-changing Serbian club Mega Basket, who in recent years have gone by names like Mega Leks, Mega Bemax, Mega Soccerbet, Mega Mozzart and now Mega MIS (all for sponsorship reasons).
