Why is it that people assume that the reason for a high score is simply to "show dominance"?
Same player scores 8-10 goals? Pointless and crass.
8 different players score goals, including those who have not gotten a chance to get into a game in who-knows-when, much less take a shot under some kind of pressure? Player development.
Players score goals but only off crosses and headers, back passes to midfielders, playing with short numbers simulating a card or two, etc.? Team development.
Realizing the other team has put in restrictions/taken out starters/tried to make it somewhat competitive and it's YOUR job to step up and try to give them as good a game as possible? Character development.
