Singles are on average a little better than walks because baserunners can advance in non force situations.
The value in walks comes from A) putting another runner on base and avoiding an out all without actually having to get a hit.
Whether it's the right thing to do or not, they will try to retool. I don't see Rogers blowing this thing up now, not with the ratings and attendance being what it is. I could see them pushing more money in to try to compete.
