I'm not worried about Porter, as I said I'm sure the Wizards will match. If a miracle happens, and he wants to join the Kings, I'm pretty confident Valde can trade Kufous to make room for Porter.
I don't think Koufos is going anywhere. Remember, he speaks Papagiannis' language (literally) and is generally considered an excellent mentor for our youngest center.
Vlade had more than one iron in the fire. Porter didn't sign the offer sheet and I suspect it had an expiration date/time. Although I haven't seen it mentioned specifically, several people on Twitter have hinted at it.
Totally O/T, I've stickied a thread at the top of the Kings Rap forum for the Twitter accounts of our players, staff and some media. If people aren't on Twitter, now might be a good time to sign up.
