As noted above the wording of the question is critical to whom to chose. If we are talking a beast inside, "owning the paint' on both ends of the court, Tina in her junior and senior years would be my choice. She won many battles during those two years against very dominant opponents. Kara Wolters was a beast for sure, but I am not as familiar with her game as I am Tina's. In a few years, Edwards will very likely be in the conversation for physical dominance over her UCONN career.
As far as the most dominant player day in and day out I have to go with Maya. She was the best player on the floor, from the first day she stepped onto it in a UCONN uniform. There were many games, where if you look at her stats, they were not overly impressive, but even during those occasions she was still the focus of the opposing coach's defensive strategy and key to Geno's game plan. She could put the team on her back and just will them back from a deficit with what is still the prettiest rise and release in the game or come from nowhere to get a put back or slap an opponents 'uncontested lay up' into the seats. She seemingly had the ability to just flip a switch and takeover a game at any given time, instilling confidence in her team and shattering that of their opponent. She didn't do any of this to feed her ego but simply to win. And that she did, from high school through her four championships with the Lynx.
