In football the gap between plays is the only "inaction". But you are virtually guaranteed action will happen after every play clock interval. You are not assured the same thing in baseball. From the time the first pitch happens to the end of the at-bat could be several minutes where very little is happening. And if a guy gets on base, you might see even more time that is milked between when he got on base and a baseball play of consequence from the next batter. Football simply does not have that kind of down time. Squeezing those step offs, throw overs, batting glove adjustments, time outs, standing and watching the signs, shaking off, etc. would do enormous good for the game. Whether it makes a sizable change in actual game time or not I don't care, the perception of speeding up the game will go a long way.
