--- Let me preface this by admitting that I am not an unbiased observer ---

I've been reading a lot of comments about Bryce Harper today. One of the themes that I am reading is that he is too immature and is a punk who is too full of himself. "If he would only change, umpires (fans, media, etc.) would treat him better."

I'm wondering how many people refuse to let him change (in their own minds). It's very obvious that he has not acted the same way the past 2 years as he did as a teenager when he got his reputation (almost a quarter of his lifetime ago), but his teenage reputation still follows him around. Will he always be defined by his teenage years? When does he lose this reputation?

For those "dislike" and "hate" voters, is there anything he can do to change his reputation?
