The following tables show Grey's preseason top 20 hitters and top 25 pitchers (top 20 starters) and their final rank according to ESPN. I also included the average draft position in both all ESPN leagues and the RCLs.
Hitters: Hanley, Wright, Zimmerman, A-Rod, and Crawford.
Pitchers: Liriano, Johnson, Jiminez, Oswalt.
Johnson, of course, was injured, so at least he wasn't putting up bad numbers.
Scherzer, Longoria and Holliday would also be considered disappointments, I think. Others fell short in certain categories, but still provided good value.
