Here's a remarkably open piece by Steve Campbell about Carlos Lee and his public perception.
“A lot of the stuff right now is a little bit of the same-old, same-old stuff about Carlos with the defense and the size and that nature. Some of that is probably magnified by the two trades we made of players who were very popular and known for their athleticism. People want to turn around and somehow shine a negative light on Carlos. I don’t think it’s justified or warranted, but it’s the nature of the public game that we play.”
Campbell points out a lot of statistics in Lee's favor, but it's basically a reminder that, if you boo Carlos Lee, you're really booing Tim Purpura.
