With the Cubs selecting seventh overall in the first round this cycle, the expectation for production jumps. I enjoy having general markers for what I would expect for the draft class (as a group) to be a success. Rounded numbers seem a reasonable way of doing that. My take is that getting 20 WAR from the draft class ought to be do-able. Anything better would be exceptional. Much worse would be detrimental.
Obviously, the top three selections ought to account for much of the "bang for the buck" in the class. Ten wins could be a realistic call from the top guy, with seven more from the next two.
