Yea, LA's post rotation should be better. But Parker's never been particularly good at defense.
I'm biased with Hartley, so I won't go there. But I'll just say that I always thought she was one of the most underrated Uconn players ever, even by the fanbase. When she would play against Sims, Diggins, McBride etc..she often outplayed them, even if her team lost. She wasn't really a typical Uconn guard though.
From what I've heard, Sammy has some personality issues. And, as fun as she can be too watch, she's too little and light to guard anyone, and her vision is obstructed. A lot of the smaller players are at least solid, Sammy's the size of a normal girl. (I think she's like 5'4 125lb) And she's not incredibly athletic. The size probably hinders her more than the personality issues. And then she's not the best shooter either.
