I have got to say, after not seeing Plum at all and DD only occasionally, that I may have changed my mind a little.
I think after seeing her last night, DD is not selfish by nature and as funny as it may sound, she does get frustrated by the players around her and once that happens, she mentally shifts off or goes into forced overload. In a pro environment with good and motivated players around her and a coach that will point out her deficiencies, she may really come into her own.
Plum did not really impress me that much. I am not convinced she can get the seperation she needs to in the Pro's. I am not saying she is Rachel Banham who I think is overwhelmed at the next level but I am not sure she will stand out at the next level either. On the other hand, physical gifts are not always the most important thing (Just ask Lindsay Whalen, Sue Bird)
I did not comment to make a choice but to highlight imho how hard the choice would be.
