Why the massive holes on the benches?

[Daniel24]

Can anyone explain why there are massive gaps at the end of most benches??? It looks so stupid, compared to the "cramped" look they have in the real NBA..

P.S- I just played against the Suns, and one thing i wouldnt mind next year would be to see steve nash laying on the floor at end of the bench (little things like this can add up to make a game so much better).
