With the new rules, I feel like the stolen base will become dramatically more important. The pitch clock will basically allow runners to time their jumps, knowing exactly when a pitcher has to throw. Also, limiting the number of pick off attempts means a runner will able to get a huge lead. I don't know that we will have a Ricky Henderson type guy, but overall I really think that we'll see a lot more attempts, which should make games a lot more exciting. The stolen base has really been missing for the past couple of decades.
