Eh, I don't hate it. Hart has come to the (rightful, imo) conclusion that this group of assholes ain't winning shit and that he wasn't gonna be able to resign Heyward. So, it's either get one more year out of Heyward, two out of Walden, and a supplemental pick or 4 from Miller and a pretty decent prospect.
What's more worrying to me is that Hart seriously thinks guys rebounding will fix our offensive problems. At this point, I'm all for trading Justin too and trying to get back some really good offensive prospects that will be ready in a couple years. Just blow that shit up for 2015 and 2016.
