um...I think you nailed it.
They appear to be plugging holes with short term deals until some of the prospects are ready to contribute. If they are able to sign Valbeuna or Moss and maybe a bullpen arm or two, then with the advancement of Stro, Sanchez, Travis, etc. and a full season of Liriano, there's a chance this team is better than last years.....all while stockpiling prospects and without handcuffing the budget long term.
