What I mean by underrated are players that are NOT in the game and are NOT Big names (Like Greg Maddux, Randy Johnson, Jim Thome, etc) who you would like in the game in some fashion of a card.
Here's some what I would like to see SDS get rights to...
Hitters: Andres Galarragga (Maybe a High Gold Flashback?), Alfonso Soriano ( Possibly a Diamond FB) Jason Varitek (Maybe Gold)
Pitchers: Dontrelle Willis (Maybe high gold), Armando Benitez (Gold) David Cone ( Think he can reach a Diamond)
I know you guys hate knuckleballers, but Tim Wakefield is my all-time favorite. He could get a 1992 Postseason card with the Pirates that would be a gold. Could also get a Breakout 1995 card with the Red Sox, also likely a low gold.
I don't know if he's underrated, as he's an MVP, but I never see his name mentioned. George Foster would be pretty cool to see the game. Don Baylor, too.
