There will probably be about 10 more things like this twitter note saying Love and KO are cool or the interview where it looks like he will stay. It's gonna go back and forth for a while. While we are more likely to not get him than get him, there is enough of shot that we'll keep reading all these things all summer.
As for KO and Sully, if we get Love things change. Now, they are somewhat playing on potential. We still don't know if they can really bring it as starters on a really good team one day. If we get Love, the question becomes can either of these guys be a good and affordable backup. I suspect they will both fall in that no-mans land of too good be be a backup for a star but not good enough to be a key starter themselves. So if we get Love, we probably start looking for good deals for both of them. We'd have a year to trade Sully and 2 for KO. Hopefully we could get a future pick with some shot of being lotto for each of them but who knows.
