If EDD had Sims covering, I really see no need for driving to the basket. That's basically an open shot.
Regardless of the size of the defender, if they are close and tight enough, which Sims would be, it is hard to get off a good shot. It is a LOT easier to get a shot off under the basket when you can turn and shoot over your defender, which BG can, than it is on the perimeter when you are facing your opponent. You have to show the ball at some point, and Sims has the quickest hands in the game. If you think EDD would be able to elevate and shoot at will, that won't happen.
For the record, have you seen Sims play perimeter defense? It doesn't get much better than that. Her defense is what makes her the best PG in the nation, IMO. Baylor has the best on-ball defender in the nation and the best paint defender in the nation. It would be tough sledding for EDD in that game.
I see no chance that Mulkey would allow BG to try to follow EDD all over the court. There is no way that BG could keep up with her in that type of defensive scheme, no more than EDD would be able to stop BG from scoring in the paint.
If EDD has to guard BG, she will foul out of that game.
