Barry sanders because he was so fun to watch.
Randy Moss in his prime with kaepernick would have been fun too. Not sure if he counts since he played for us but he was washed up when he arrived.
Reggio white was a monster.
Lawrence Taylor would be my other big one for defense.
I'm also a big ed Reed fan so him in his prime or Merton hanks for style points.
Future hall of famers I wish played for us? Aaron Rodgers before kaep and Calvin johnson.
