I am really starting to feel that the front office is going to treat this season as a developmental year. The complete failure up to this point in putting together a starting rotation (with a payroll under $100M) seems like an indication that we will see a lot of prospects getting significant time this season.
I'm expecting to see a lot of the prospects who have already made their MLB debuts (Ryan, Ober, Jax, Moran, Kirilloff, Larnach, Rooker, Celestino, and Gordon) make the opening day roster. I would also expect to see a significant number of the Lewis, Martin, Balazovic, Richardson, Duran, Miranda, Winder, Canterino, Sands, Henriquez, Vallimont, and Strotman group fairly early as well. This is the year where we really find out how good Falvey and Levine are at scouting and developing talent (with a strong emphasis on the development of starting pitching).
I won't be surprised to see Donaldson, Sano, Rogers, Bundy, Duffey, and Thielbar getting moved for prospects by the trade deadline (or even before the season starts in some cases). I even wonder if Polanco and Kepler would be available for the right offer.
