I was listening to the conversation during the radio broadcast today about the rules at second base, and how it will force the fielder to keep his foot down longer, which in a sense adds to the risk to the player that they are trying to protect. Why wouldn't it be feasible to add a fielder's bag at second, not unlike what lower levels do at first base? It could be very small, but a protected square for the fielder's foot. You slide directly into it, you're ejected. It still allows the legit slide into the primary bag, with the body to do the takeout, but adds a little time for a reaction.
