Only thing that I can think of would be if they weren't in the bonus yet. If not in the bonus and team with good 3pt shooters it allows them to stop the 3pt shots as well as get them into the bonus if they happen to end up trailing.

It they were already in the bonus the only other thing besides the 3pt issue would be that they didn't think the other team could shoot free throws well and they thought they could make theirs.

Just a few thoughts.
