You let Mikhayev and Dermott walk? also, the Kuemper trade though it is a nice touch, why would Arizona need Holl when they already have Demers, Hjalmarsson, and Goligoski on the right side and Arizona have no money to support both a Holl or Andersen contract unless if someone substantial gets moved out of the desert. OEL probably?

traded Dermott for weaver

I'd be willing to bet Weegar gets twice that for at least three years. He's also worth at least twice what Dermott is worth.
