At some point time becomes an issue. Especially with traveling coaches. In most cases now it is not needed for any purpose but to save time when the game is out of reach.
However, in the past, we did have some coaches running it up for whatever reason, mostly to pad their statistics. When you lose 50-0, 48-0, some coaches, especially newbies, you could rest assured you would lose a coach or two. Now, those same coaches understand the professional courtesy that is necessary to not only keep coaches, but to help them in their development. It makes me very proud to say that.
Rounded bases? In this league. It is hard enough to stop the square ones. The game is solid as is with defensive struggles and shoot-outs. It'll just be shootouts. We re-evaluate our rules every year and make changes based upon the development of the coaches, impact on new coaches, etc. Hope this helps.
