If you think about it, there are a lot of times returners bobble the ball....maybe not as excessively as Jacoby Jones did for the Texans, but nevertheless, you have to make it a rule to protect the returner and keep a total judgment call away from the refs. If there is a slight bobble, then you would leave your returner exposed to get obliterated by the punt coverage if that wasn't a rule. You would have heads rolling all over the field if that was not a rule. It was a good call by the refs in my opinion.
