First off, this was based on watching that game, so I confined myself to last year's team only. (I have often thought, over the last 5 years- man, if we had Dolson, we'd have won 9 straight NCs!)
When you watch that tOSU game (or any game last year, I'd assume), you remember how aggressive and fast Crystal was, how she could get her own shot, how she could shoot from downtown as well as penetrate, and how well she defended. She was 3+years seasoned in the system. Granted, she was plagued with making a bonehead play or 2 a game, even as a senior, but overall she had a veteran game.
So, CD would have added: experience, 3-pt shooting, speed, aggression, perimeter defense. Also 118/52 A/TO.
ETA: CD was also very strong, tough, and in great condition.
