travis hafner might be fair, but that mo vaughn schtick is ridiculous. fielder works way too hard to be reduced to that kind of fodder. even then, from all public conversations i've been privy to, hafner is half as smart as fielder. realize this is intangible bs, but it still must be considered. mind doesn't stop a bad body from breaking down, but if a guy has a will and work ethic, he is more likely to buck the trend, & with fielder i think he is as good of a bad body to do so as baseball has seen. i'd say he's more between hafner and a guy like frank thomas.
