Comments on Attributes (please take this ONLY as constructive criticism, as you do an awesome job - far better than I could ever do). I was also wondering if you use a specific database as a reference.
Being a Met fan, here's my review for their MLB team:
Jason Bay - his numbers vs rhp should be lower than his numbers vs lhp
Daniel Murphy - his batting ratings seem too low
Kirk Niewnhuis - his batting ratings seem too low, especially vs rhp
Reuben Tejada - batting ratings too low (he's batting 325) and his fielding ratings should be better
RA Dickey - his knuck control should be increased, and is there any way to add a slow knuckler (maybe as a knucklecurve)?. Also his pickoff move is pretty good, and you have him as 0
Jon Niese - He should have more control, especially on his cutter
Johan Santana - Changeup speed should be slower (avg speed this year is 77.4),
Once again - you do an awesome job, and I'm just trying to be of help.
