IDK, the projections seem fair enough to me. It's a projected .727 OPS, which is ok BUT NOT ENOUGH TO WARRANT MOVING HIM OFF POSITION.
Again, he's more valuable at C. The only way he gets moved to 3B is if his yips don't go away or he really struggles behind the plate and becomes a lost cause. A player with his hit tool playing 3B, isn't really a prospect that you refuse to trade the way the Sox have done so far. Moving him off position was a mistake last year and would be a mistake this year too.
