MLB has to make games easier to watch. They need to be more available to watch. Making it more difficult with blackouts and exclusive TV rights is asinine. No other industry that I'm aware of makes it MORE difficult to consume their product than professional sports and MLB in particular. I like what the NHL has done and I think MLB should take some lessons from them. It's awfully difficult to maintain a fanbase, let alone grow it, if people can't watch.
On top of that, a pitch clock is such a simple way to speed things up. You don't even know it's there. Of course, it would actually have to be enforced, but the benefits to the minor league game are obvious.
