I don't get the "since Donaldson was traded for not very much, every 3B value goes down". Also, if RH power is worth so much around the league then I think EE should be higher.
Stroman should be higher than Ventura I would think as well, but I guess the "being short" would decrease Stroman's value around the league still.
Edit: Lucroy should be way higher. If Martin was getting 70 million dollar offeres from multiple teams, than catcher defense is worth a lot more than Dave Cameron thinks.
