Well, I think we've got a $hit-stirrer here, but I do agree with one point:
…every joe shmo can be an analyst...
Yup, too many 'Joe Shmos' out there blogging away who don't have a clue. Some of them are wielding saber-metrics (and giving it a bad name IMO) and too many of those aren't accounting for the grinders that can make the game great.
I really don't care what anyone says about this - there is such a thing as "heart" and there are players who have way more of it than others. Sabre-metrics or not, I'll take 'em on my team. They know how to win baseball games.
I'll suggest that heart does show up in sabre-metrics. The guys with heart, work hard and get results. They may not be showy or have the "body" but they are effective and the numbers prove it.
