We also have a subcommittee on protective equipment that meets on a regular basis. We're constantly evaluating.
I know a lot of people talk about helmets. Concussions and helmets are two different things. The concussion is what happens inside; the helmet keeps you from getting a cracked skull, but it doesn't necessarily stop a concussion. But we have subcommittees that meet on a regular basis to deal with and look at equipment and what changes are appropriate, and we continue that.
All these things that relate to the game are not one-offs. This is a constant effort where we put personnel. Time, energy and money is spent to continuously evaluate what's going on in the game and to make the best judgments for the game.
