It's pretty useless to speculate, as it can be pretty much anybody.
A little off topic, but I'm curious as to what you guys have to say about this..
I think one thing everyone overlooks in the Giambi/Sheffield/Bonds- Balco thing. I hear people often say that these guys cheated.
Now, if I'm not mistaken, cheaters are the ones who break the rules. In this instance, there were no rules to break, what they were using was allowed by the MLB. That isn't cheating. It is immoral, yes. But not against the rules, and not cheating. Palmiero getting caught and suspended, that is cheating. I agree, what Bonds and Giambi did was wrong, but cheating wasn't what they did. And we can't have ex post facto laws.
It's similar to the Yankee's ridiculous payroll IMO. It's not right and it certainly shouldn't be allowed, but it is. It's not ethical for the Yankees to have a payroll 15x that of the AL Central, but its legal and it isn't cheating.
Thoughts?
