I really like Carol, but sometimes her mistakes annoy me. She's great at spiking and serving and she's good in defense too. But when it comes to setting, I think she has too many ups and downs. Maybe in NT, with better receivers, her game will flow better. I have the impression that technically, she has a lot to learn when it comes to setting, but her ball's distribution is better than Ana Tiemi's. That's why Tiemi is in the bench.
Carol has a lot of potential, in 2005 and 2006 she was playing very well, even in 2007 when she was in the NT she played well. After being dropped out of the NT, though, I think she has never reached her previous good form again.
I really like Carol but she needs to do her part, she has to improve her settings if she intends to be in the NT's roster.
As for Dani Lins, it goes without saying that she improved, but as Lothie said, it will be wiser for her to join the NT in 2009. If I were the coach I would call Fofáo and Carol this year and in 2009 the two setters would be Fabiola and Dani Lins.
