Is there a scenario where OPI and DPI can be called on the A and B in the same play? Are there good examples of this in the past? I have only found one example, 2012 TCU vs WVU, where the pass was incomplete anyways, so it was a replay of a down and the outcome was relatively benign (1st down, halfway through the 3rd quarter). I'm not sure that I agree with the call, I would likely have kept the the flags away. In that 2012 example, the flags also came from separate judges.
What would the requirements be for such a situation? I would think that any situation where B interferes with A while the pass is in the air, followed by A interfering with B, would be 1) PI on B for initiating the interference or 2) no flags on account of mutual combat. The other implication is that if A catches the ball but it's a replay of down for offsetting penalties, there is a clear advantage given to B.
Would love to gather thoughts on this.
