I think Davis will cool off a bit...but he's not an automatic sell high, as in, he could help you out the whole season (with a few bumps in the road)...
...I'd start the ball rolling with offering Davis for the likes of Samardzija, Gallardo, Harvey in that order...pick one...or another pitcher...target an owner who is struggling in the hitting department and target a slow-starter or up-and-comer...
...find an owner that's willing to talk...then add Tillman or Maholm to the pie (in that order)
