That's certainly your opinion. Problem is that every time someone (a poster or an article) says something you don't agree with, you say the info doesn't say anything, or the logic isn't sound, or(in this case) that what is said destroys his credibility, or whatever else. As if everything said that you don't agree with is invalid or bunk and the source isn't credible. That's hardly the case. As far as who he is, Senior writer at Fangraphs, co-managing editor of the Hardball Times, writes for ESPN Insider, worked 7 years for a MLB ball club, and someone whose opinion is valued enough he is asked to do a chat by a major sports site. HIS credibility isn't in question.
