After witnessing 13 years of Gardy's reign of terror, my oservation is that once a guy was anointed as the starter at a position they wouldn't move barring an emergency. I'm remembering Delmon Young entrenched in left field despite grading out better in right, and even when Cuddyer was primarily playing first base due to Morneau's injuries. I guess we'll never know, but it always seemed to me like Gardy liked having a guy play one position and only one position.
