One reason you typically don't see really hacky/exploitative stuff in competitive sports is that... these sports are decades or even 100+ years old. Tens of thousands of games have been played by extremely talented and competitive individuals. Thousands of exploits have been tried and written into the rulebooks.

For example, the "Sean Avery" rule in hockey.

That was a neat "exploit" and much respect to him for trying it, but it was outlawed literally the next day.

    The incentive to pull off this kind of move, 
    running the clock down a bit, that was already 
    present. But there's a certain social 
    expectation that you won't game the rules so 
    blatantly, so that's a disincentive.

While a fun thought, I cannot understate how incorrect this is.

In basketball, football, or basically any sport with a time limit there is absolutely zero stigma or shame with regards to running out the clock if it benefits your team.

In fact, that guy would have been raked over the coals if he didn't run out the clock.

I also assure you his coach was exhorting the team to win the game by running out the clock rather than scoring with time remaining on the clock which would have given the other team another chance to score and perhaps tie/win.

I'm sure that player definitely did pull that move off in a video game, but so has everybody else, because it's also super basic football strategy!
