I know it’s a long-shot, but I hope they take a real shot at Machado & Harper. If you miss on those guys, maybe look at a veteran CF, 3B, or 1B/DH on a short term deal. There is the makings of a pretty good offense if they keep Abreu & Avi and make the right additions.
Pitching will have question marks, but I still think I’d start the season with a rotation of Rodon, Kopech, Lopez, Giolito, and either Covey or Stephens. Add veteran reliever or two to stabilize the bullpen, but otherwise roll with a young staff and wait for the next wave of guys (Cease, Dunning, Hansen, etc) to serve as reinforcements.
