I just disagree with the idea that the vast majority of what he says is positive. I posted the statistical updates because they clearly illustrate Jacko's willingness to post negative things about the Yankees, an idea you seem to be disagreeing with. Furthermore, he has posted numerous extremely negative threads about the Yankees, essentially saying their season is over, in past years. I'll admit that, with the scouting reports, he has had his moments where he focuses on the positives when it comes to Yankees' prospects, and the negatives when it comes to Red Sox's prospects.
On the whole, I just think Jacko's bias is overstated. He's not your average idiotic Yankee fan who just covers his ears and yells 'YANKEES RULE, RED SOX SUCK'. That's not to say he doesn't have his biased moments, which he does, but no more so than most of the members on this site. Now, I completely understand that it's acceptable from a Red Sox fan here, because it's a Red Sox forum. I have no issue with that, but it just gets frustrating when every conversation involving Jacko turns into people calling him biased when a) that feeling comes more from the accepted narrative about Jacko rather than what he's actually saying and many of those people are guilty of similar things.
By the way, on a separate note, we never revisited our Yankees' money/salary cap debate ... but point to you, after having given it more thought I'm completely in favor of MLB team salaries to be capped (and floored).
