Osafor, playing UConn, would not be much of a factor I don't think. She is a great player, she has a very unique shooting technique, she does have good footwork, and obviously incredible strength. I don't see her getting off too many of those three point shots against UConn. The pace at which UConn plays would have her very tired within the first couple minutes. Though she is a great player and has overcome a lot, I don't see her being a big factor in the game.
Kelsey Plum may get her shots and may get her points, or she may not. I could easily see Moriah blanketing her. She's good at getting to the line so Stewie and Morgan especially would need to have perfect block position in the paint.
I'm not entirely sure about Walton. Debbie Antonelli compared her to Marissa Coleman in one of the games in terms of body shape and strength. Seeing her, I would argue she has similar scoring abilities as well. She's an excellent three point shooter, she can rebound, and she can score inside.
Overall, while it would be fun to have two Husky teams playing for the championship, it will not be much of a game.
