I project Rendon as Edgar Martinez and Goodwin as Curtis Granderson with 25 homers instead of 40+ (2008 Tigers type season)
You're kind of making my point for me.
Edgar Martinez' top two seasons by WAR: 7.5, 6.5
Curtis Granderson's top two seasons by WAR: 7.8, 7.0
The other tools are meaningful.
However, I agree this is an open debate. Prospect rankings are kind of silly.
