AGAINST...Here's why: First of all, it is more than likely impossible to come back when down by 40. But when a team is up by this much, this is when 2nd and 3rd string get playing time. A coach needs all of his players to play in order to have leadership in the future. If this rule was put into action the game would change from a marathon race to a sprint. A coach has to use his subs effectively in order to win a game. This rule would turn the game into who could get up by 40, rather than who can play 4 quarters of basketball. I don't see this rule being adopted.
