No, no it won't. She's not ready, period, to lead a championship caliber team. Did you see the East suddenly stall during the West run to force overtime? Who was the point guard for the East that turned it over?
In fact, I'd say Karleen Thompson would really irritate Cooper if she did. Cooper point blank said on the Dishin & Swishin he did with me that he fully expects Dumerc to be his point guard, and that Dumerc needs to be for them to win.
Look, I get the Shoni love, and having interviewed her on several occasions I can tell you she is a great kid.
There is a reason Dumerc is one of the top point guards in the world; she gets the ball to people in the right places regularly and consistently.
There is a reason Thomas played more than Shoni, and that is defense; Thomas does it well.
Let Shoni be Shoni, come off the bench as instant offense. In some games she'll play 20, in some games she'll play 10. As Striper69 said, let her learn.
The 2014 Atlanta Dream belongs to Angel, Erika, and Sancho...not Shoni. Her team may come, but if they want to win now, keep the ball in the hands of the veterans.
