Courtney will enjoy the best of both worlds.
1 - She takes with her two years of learning how to play the game UConn style, and having been tutored and coached by one of the best college coaches of all time. She leaves with not 1, but 2 championship rings in her back pocket that no one can take away from her; she earned those. She'll take away the experience of preparing for, and playing in six games in the NCAA tournament twice. That's something most players never get to experience once.
2 - She's going to finish her college career at home, playing in front of family and friends on a nightly basis. This dynamic should not be taken lightly. There's no place like home. Her chances of getting more playing time just improved exponentially with this move.
Looking at it from several perspectives, all I can see is a win-win for Courtney. I don't see any down side or negatives to her transferring to ASU. Any time you return home, it's always nice. Just ask Moriah Jefferson who returned to her personal "briar patch".
