Baseball has changed a lot over the years, in good ways and in bad. There are two sides to most of these problems. The first problem is the new rule of instant replay and challenging calls. Baseball is a very long game as it is and I think that instant replay is just going to make it longer. The second problem is the rule of no contact at home plate. I fully understand that the players can get hurt, but the catcher is in full gear and it wont hurt him that bad. I think they should get rid of this rule because it just shows that they are weak. I think that if the players want to run into the catchers, it is their own chance that they are taking and if they get hurt it is their own fault.
