Where and what do we have next?

[BoBo]

Thanks for confirming my thoughts.

For some reason I am brainfarting on this tonight.

A ends up short of the line to gain. Say 3rd and 4.

USC like on B first and then USC on A.

We march of the 15 yards on B first. This now results in a 1st and 10 for A.

Then we march 15 yards off on A and it is still 1st and 10 provided no half the distance walkoff on B first.

Man I think I am tired and need sleep. I am going to hunt for the rule books and clarify this.
