These links are ones that I find interesting and read-worthy(is that even a word?). If you have a suggestion for a link, drop me some mail and I can add them.

SABR Specific

Rob Neyer - Author, ESPN writer and messenger for the SABR gospel, Neyer writes a daily article for ESPN which is a must read.

Other Blue Jays Sites
Batter's Box - A Blue Jays blog with a good following and lots of updates. The end of the month grades that they give are always amusing, though not always steeped in analysis, but overall a very good site.
Blue Jay Way - Blog sites about the Blue Jays are abound it seems, I haven't visited this one too much but I like the layout and forum.
