Disagree. You value a prospect not by what he could do, but what he could/will/might do when compared to others at his position
When comparing Alonso's ceiling, floor, and likely production with with the 1B already in the major leagues, in the high minors who're likely to be in the league with him, or the "value" of said prospects below him, Alonso should be negged a bit for Votto's performance. It affects his "value" to the Reds (as a trade piece and as a major leaguer) and as a 1B overall.
