For me, this statement is a gross over simplification. It takes a lot more than "fighting" to win a game. It also takes a lot more than just a "will to win." If you wanted a relative simplification, basically for a period of time, Duke's shots just didn't go in. ( 0 for 12 or something like that.)
If you broke the game down into four minute segments, there were segments that UConn won, and segments that Duke won. For those segments that Duke outplayed UConn, would she say (or anyone) that UConn didn't fight? No. UConn just made some dumb passes. It happens.
If McCalllie were being honest, she would have said that her game plan didn't work, and she didn't adjust. It appeared to me that the game plan was to play a sagging zone, with double coverage of Stef inside. They left KML alone, because she hadn't played for 8 games, and was just coming back from injury. Not a bad assumption, but it didn't work. And Duke didn't adjust fast enough.
One of the reasons that McGraw and ND were successful against UConn was that ND usually had a good game plan for UConn, and if it wasn't working, they changed to something that did work. IMHO, McGraw (sp.? too lazy to look it up.) is as good as Geno at making halftime adjustments.
My observation is, there are very few women's coaches who are willing to take responsibility for a loss. (Men's coaches too, maybe.) As a former coach, I can attest to the fact that sometimes players just don't do what you coached them to do. But at the same time, a coach needs to constantly assess their game plan, and think about what they can do better to help their team have a chance to succeed. Saying that their team wasn't willing to "fight" for a victory is non-productive in my opinion.
Okay, now I'm starting to ramble, so I'll stop here.
