Frankly, I support the idea. Just think of how much it would "clean up" the end of a close game. Defenders would have no reason to foul unless it was the result of them going for the ball. We wouldn't have all this controversy about whether or not a foul was intentional at the end of a game.
A lot of guys say that fouling at the end is just "part of the game". Well - it shouldn't be. Committing fouls on purpose is not what Dr. Naismith envisioned. I ought to know - I asked him personally.
