I was an Adam Dunn fan as soon as it was fashionable (his final minor league year) and a Justin Morneau fan from rookie ball (Twins fan here). I always believed Morneau was a .300 hitter based on his minor league numbers. Now, watching him everyday, it's very obvious that he is a .300 hitter. I can explain why I know he is now, but I choose to not bias my question.
I didn't watch Dunn from rookie ball on, but given John's recent retro, my memory is that Dunn and Morneau were very, very similar. Assuming for their primes that Morneau is a .300+ hitter and Dunn is a .255 hitter, what foretold the difference?
