To use more relevant numbers, Sandoval has been worth 13.4 wins in 523 games the past 4 seasons. That translates to about 3.8 wins per 150 games. If he could manage to stay healthy enough to average that many games, at that pace he'd be worth about $114M over 5 years. That obviously doesn't take into account decline or a likely position change if and when his body worsens. So yeah, I still don't think he's worth that contract at this stage, but it's probably not as bad as you're making it seem. a win on the open market is looking to be much closer to $7M right now
