If, and it is a huge if, the Twins can get their starters healthy and have a rotation of Gray, Ryan, Smeltzer, Ober, Archer with Winder filling a role, they have a competent, but unexciting rotation. I submit they need two bullpen arms if they really want to compete with the likes of the beasts of the east and Houston. Tier One: Duran + two acquired BP arms. Tier Two: Pagan, Smith, Thielbar, Jax, Moran, perhaps Megill.
