The thing is that most people who boo Lee aren't doing it "just because he's an opponent." They're doing it because they think he somehow jilted the Brewers, and that thinking is just wacky. Yeah, this is a complicated one. I mean, I think he eventually would have jilted the Brewers, had he not been traded to Texas. (Check that: I know he would have jilted the Brewers.) Then, in my mind, he would be boo-worthy. But I think the trade was sort of like the George Costanza preemptive break-up -- the Brewers broke up with him before he could break up with them. So I don't think he should be booed for that. Also, as has been mentioned earlier, he was a solid teammate and decent overall citizen during his tenure in Milwaukee.
