OK, I have finalized the 2013 Marcel’s data which Tom Tango may or may not release this season:
Also, the data has been added to the Marcel comparison tool (looks for similar players and how they produced in the year of the projection - a way good to find % chance of under or over performed).
With the default values, Trout had no comparable 22-year-olds. By spreading out the criteria, I got 3 comps since 1952, Hank Aaron, Frank Robinson and Miguel Cabrera. Not a shabby list.
