1 - EDD just won the MVP and she started at SF. She probably played more PF than SF but she played both quite a bit. She almost never played C. I can recall a few times where they tried she and Breland and 4&5 and in those situations she may have guarded centers because she is a little taller, but offensively she was not playing as a center. That configurations stopped entirely once they got De Souza, mostly because it didn't work.
1B - EDD can play center but she's not very effective at it and it's certainly not the way to get the most out of her.
2 - Chicago had the 2nd highest pace in the league. They also had the best per-possession offensive and EDD won MVP and had the best PER in WNBA history this side of Lauren Jackson. She absolutely thrives in a team based on pace.
Subjectively, I think she may be the best transition player in the league because she's such a threat with her deep ball (I know the numbers were down this year but look at her career numbers). Pretty much any highlight reel of EDD's will feature a transition 3.
I agree with you on 3 and 4, but I strongly disagree on points 1 and 2.
