Uh, no. That's not a logical comparison. You are comparing two completely different situations.
When the outcome of the game is in doubt, you play strategically. You don't gamble unless the reward is worth the risk.
When the outcome of a game is not in doubt, you can take risks because it won't cost you in the win column, and doing so is a good way to give certain players reps (such as backups), besides fostering confidence overall (why not go for it when the coach trusts you to execute?).
Moreover, there doesn't even have to be a justification for it, because it's only the feelings of certain fans that get hurt, and who cares about that, really? Regardless of whether fans hate it or not, certain teams do it.
