I was a pretty big A's fan as a kid. Went to a lot of games, and just loved those late 80s teams.
My favorite players were McGwire (tarnished memories now) and Dave Stewart, but they were all great. Canseco, Rickey Henderson, Terry Steinbach, Carney Lansford, Eck ... the list goes on.
For Saxby's sake, let me just point out that Dave Stewart absolutely owned Roger Clemens in big games.
