If we take audience selection into account, then the defense at position 3 is limited to 2 options.

Taking this into consideration, we have 1*6*2*4*2.

For example, if category A was selected as the 3rd defense, then it would be unavailable for any of the other positions.

This gives us 96.

Squaring 96 gives us 9216... which is precisely half of the number presented. I don't know where that extra 2 came from. If anyone could care to enlighten me, that'd be welcome. From what I see if 10980 combinations were played we've played more combinations than are available. Just my take on the issue.
