I see the value in Drew defensively and his ability to get on base. He's not going to hit a lot of home runs and he's definitely not going to steal bases, so you'd probably want to put him in front of someone who can drive the ball into or over the wall.
You continue to come back to the 20X the cost equation. As Spycake has stated, Drew's offensive WAR contribution clearly outstrips the premium cost for a proven major league bat.
In answering your question, "...but at what price?", my answer is simple, one the Twins demonstrably can afford to pay, and just as importantly, incurs ZERO cost that could hinder the long-term plan for the club.
