As much a part of the problem as fouling is the "defense" of the team with the lead. It's like teams are so scared of fouling, they just start giving up baskets late in the game, which allows the trailing team to continue to score at a quick rate, and keeps the game within reach. I don't get this over-fear of the foul by teams leading. If you actually play defense and run more clock, and force tougher shots, that's worth possibly fouling, compared to giving teams a quick, easy layup. Hell, I'd rather foul than give a quick easy layup.
