In certain modern team sports there are a number of what we may describe as normative, yet legal, "desperation moves" that the team losing a contest may attempt as time begins to run out — provided the deficit is reasonably surmountable. In hockey, for example, the losing team will pull the goaltender in favour of an extra attacking skater; in basketball, a team will foul deliberately in order to force the other team to immediately shoot free throws; in gridiron football, there is the onside kickoff, etc.
Strategically, we might abstract these three examples as follows: in hockey, given the particular status (and equipment) that characterizes the goaltender, the attempt is to create an asymmetry in the number of attacking skaters and put pressure in the opposing zone. In basketball, constrained as it is by a required player symmetry, the attempt is to dilate the temporal parameters of the game, "extending" it by rapidly fouling and hopefully trading off multiple 1-point shots for 2- or 3-point shots at the other end. Gridiron football is also constrained by symmetry, on the one hand, but does not have regular and rapid turnover of possession either, and thus its attempt with the onside kick is to overload a space — or more precisely, to swarm a proximity.
In each case we witness a malleable, plastic quality — stretching, contracting, spasming — that over enough contests will have a statistically significant ability to turn the tide of victory in the timespaces of zero-sum athletic enclosure.
