Batty - I actually agree with you on the discouraging the collisions.
Noumpere - If you are pointing to my example in your #3 above I agree the BR was out at 1st base. Problem was it was Bases loaded 1 out, tie game bottom 7. So when runner on 1st was awarded 2nd base the runner from 3rd scored. Instead of inning ending DP game goes to extra's it became a walk off circus.
