What does this mean? Well, for one, you can end the "automatic" talks of us getting a 1st and 3rd-round pick for Anderson, because other teams can no longer sign him. And, assuming we've given Anderson money guaranteed, I highly doubt that we'll be looking to trade him this year.
I'll be updating this post as more details come along.
Update [2008-2-29 12:15:49 by ChrisPokorny]: Anderson's deal appears to be around 3 years for $24 million with about $12-$14 million guaranteed.
