Sounds great but what happens when some players start ignoring the whistle and others dont? They'll be injuries. The whistle is there to stop everything immediatley for a reason. SO that everuone knows to lay off the full bore action. If officials could do a better job of not ending plays prematurely then there would be little need for a rule which could lead to increased injuries.

That's what I doubt.
