There is no way to model this, since half the players do better and half do worse, But figured Contreras, Raffy, Abreu, Durbin, and Mayer don't surprise me with the +/-. Wong & IKF don't have enough PAs to surprise one way or another.
But I was surprised by just how far off Duran is and should've included him. I've done this exercise before, but if Story, Narvaez, and Anthony hit their FG projections, the RS would have a .721, good for 16th. If we include Duran reaching his FG projection, then our OPS is .738, good for 7th.
