Poor Kristy is going through some stuff right now. I read somewhere that she lost her stepmom to cancer a few days ago. Dunno if it's true or not, but if it is, I wish her nothing but the best.
As much as I wouldn't mind seeing it, there's no room for Marina in Indy now IMO. She'd get about 5 minutes per game playing behind Caitlin, Kelsey, DB, Lexie, and Sophie. Plus, like you said, I don't think the Sun are too keen on letting her go right now. Indy would have to give up something to get her, and now that the superteam has been assembled, I'm not sure who they could part with that would leave them better off, even if Connecticut was willing to do a deal.
