They intended to redshirt Morrison, but there were other factors at work and they ended up playing her. You can just say I was wrong or whatever, no problem. I can't tell the whole story because it would violate a confidence, so I'm fine with just taking a loss in your book.
When the NCAA moved to the regional/super regional format in 2005 to match the baseball tournament's format, they adopted all the of the same rules as baseball, including the rule that stated a team could not be forced to play three games in one day. That's why, when there are weather delays, you ALWAYS see the baseball tournament play the third "if necessary" game on Monday instead of Sunday.
When ESPN re-upped its NCAA contract that covers the softball tournament (it's a larger NCAA deal that covers all sports other than women's basketball), they asked that the provision that the "if necessary" game moving to Monday be removed from the rules. ESPN made the request because they're now on the hook to televise at least six of the 16 regionals (as you've seen, in the two years since they have expanded their coverage beyond the minimum), and did not want to incur the extra costs of keeping a truck and crew at a site for an additional day. The NCAA quietly removed the rule and many coaches were not even aware of it until much later. I know for a fact that Coach Lawson at Kentucky was not aware of it until her team faced the same possibility this weekend.
I updated my post in the thread after I found out the rule had been changed. As I understood the explanation I received, the teams should have played the additional game on Saturday night, leaving Sunday exclusively for the regional championship and if necessary game, as was done at Kentucky. But that format was not followed here after the NCAA reps consulted with ESPN.
