The top Russian league has franchises owned by rich [VERY rich] old Soviet thugs who like watching girls play basketball and crowing over their rivals by beating them. One owner insists on coming to lots of practices and putting his hands on the girls. Since he doesn't insist on anything more, they put up with it and smile at him.
Because the Russian A-League is a bidding war, the US and Aussie girls emphasize their schedules there, often delaying showing up for the WNBA season until the Russian league is over. WNBA teams have tended to begin seasons stinking the courts up, and suddenly getting way better. Other teams have lost key players permanently. A third issue is that few non-US players are bothering to come over here at all --- part of this is salary, but part of this is that they don't feel welcome on the teams [feeling prejudiced against at least to a degree --- all this is "out there" if one is willing to work at digging the frank commentary out.]
Jewell MIGHT have reasoned this out this way: Get drafted high/ make a few bucks/ impress a Russian Money Daddy with her WNBA season/ go overseas and make some real money. I hadn't put those pieces together, but that could make pragmatic short-term economic sense. I don't know if Skylar is yet doing this, but if she is then that could have influenced Jewell.
