This question came to me a while ago because Pence and Braun were tearing it up for my team. Pence has been awesome, but I haven't seen a rookie with Braun's fantasy output in a long...ever, I guess. That got me thinking since I've only played fantasy baseball for 4 years...who has been the most impactful (is that a word?) rookie ever in fantasy baseball? I'm voting for Braun (with limited knowledge) and giving Liriano a close second, and only because of his injury. Thoughts?
