Because they want something in return for doing something that benefits their membership... At first the rule was said to effect players on the 53 in week 1, but apparently it was actually going to allow for one guy injured after practicing in camp to go on a 6 week IR.

The NFLPA agreed to HgH blood testing, too...only in the year since they haven't agreed to a standard method of testing which is clearly just a stall tactic. They don't give a rats you know what about player safety or rank and file players, it's all politics and billable hours to these guys.
