I have edited all the AL "great" players to become real players, most of whom are very similar to the "great" form. Here are the changes I've made. Reply to me if you've thought up a better change. (If you make these edits, you may want to change the handedness and appearance. Most of these guys have a Voice. '07 stats in parentheses.)
Red Sox G.Reyes : George Kottaras #68
RS 1B G.Lopez : Jeff Bailey #55 (.111/1/1)
RS G.Harris : No other good Sox catchers. I made LF Chris Carter #54
Yankees G.Gordon : Wilson Betemit #14 (.229/14/50) C Speed is a bit generous for Betemit

O's G.Thompson : Jamie Walker #32 (3.23)

Indians 2b : Josh Barfield #29 (.243/3/50)
Tigers G.Roberts : Freddy Dolsi #32

NL Greats coming soon!
It really is worth the time to edit these, just to know that all the players you're using are real.
