Hey, I love this. Biggest surprise (for me) is Red Sox 2nd base.

A few comments/requests:
1. Are you going to do something similar for pitchers?
2. Can you add a sum on the right, adding up each teams' accumulated WARP?
3. Can you remind us how many wins a baseline replacement team would be expected to put up? Such as note somewhere on the page that a "replacement level team" at this point in the season would be expected to have X wins?
4. Does the math involving #1, #2 and #3 above generally line up with reality? I understand teams often outperform/underperform their numbers, but generally speaking if you add up a team's individual WARP is it close to ten extra WARP being equal to ten extra wins? (I am familiar with WARP and the rule of thumb that 10 runs equals one win but know stats are more complicated than that.)

But those are not complaints. This is a great visual tool, between this and the Prospect Tracker you guys are on a roll this year. Incredibly interesting and helpful tools, thank you.

Awesome-what do the colors mean? I see some 0.0's that are green and some are red.
