This is pretty cool, but some of that stat choices are a little curious. VORP instead of WAR? No park- or league-adjusted offensive stats like wRC+ or OPS+? No defensive stats at all? No BABIP or batted ball rates for pitchers? It's hard to do any in-depth pitcher analysis with only FIP. I really like the ability to compare up to 4 players on any given stat that's available, but the choice of stats is kind of lacking…

Do you have any input on the BE Score?

As a baseball fan and fantasy baseball player, I hope you don't mind if I say that I am not finding this site very useful (or am I not able to figure out how to use it effectively.) For instance, given that we are only 3 (or 4) days into the season, showing 2012 season stats is not very useful yet. Showing projections might be useful -- you don't even have to make your own projections, as there other well-known projections out there such as Bill James', ZiPS, Marcel, etc.

Another issue is that selection of stat categories for the "BE scorecard" does not match up with most fantasy baseball 5x5 leagues since it is missing AVG.

I think the idea of bringing more data visualization to baseball is great though. This is actually the topic I am using for my class project in my data visualization class (due in a couple weeks now!) I will definitely keep an eye on this site though, and hopefully you will continue developing and improving it.

Thanks for your feedback. The site updates once a day, so tomorrow there will be more data

Do you have any input on the BE Score?

This is a tough question to answer. The fact is that your typical fantasy league is going to value stats that have little predictive or descriptive value such as RBI. I think that the BE score would be a good metric for how valuable a player has been in one of these kind of fantasy leagues in the past. However, if you're wanting the BE score to be predictive of future value to a fantasy team, what you're really trying to project is future performance in general. If you want to get into that, the inputs that you have aren't sufficiently predictive and you're going to have to lean on more advanced metrics. As far as I can tell, BE weights all of the 7 stats exactly equally. The truth is that RBI is a terrible stat and VORP is an okay stat, for instance.

There are some really smart people out there working on projection systems that you could look into. Dan Szymborski does ZiPS, Tom Tango does Marcel and then you probably know about Bill James who has a projection system by the same name. There are others, but these are probably the most popular.

I'd love to offer my assistance; baseball nerdery plus development nerdery would essentially be my dream job, but I would be way too swamped until June or so to be able to contribute. I don't know how SABR savvy you are, but my contact is in my profile and you're welcome to bounce questions off of me. There are also tons of resources out there I can direct you to.

Very interesting idea - I'll have to introduce it to one of my friends :) You wouldn't happen to have football a fantasy football branch in the works, would you? One complaint: on the root page, the right (?) puts text off-screen, and you can't scroll to view it because that hides the text.

What do you like about this version that you would like to see in the football one?

Tyrone, first of all I love the data visualization efforts. As a personal baseball stat nerd myself, I always appreciate a site with in depth stats.

As for a football version, since the format is week to week you should heavily consider incorporating weekly matchups for players (ex. Arian Foster vs. Indanapolis Colts Defense, at home). There are a few good resources that I could direct you to for projecting matchups, but if you made your own incorporating split stats you could honestly provide a great resource to fantasy owners and, with the right marketing, capture a good portion the fantasy football market.

Positions are much more important for fantasy football than they are in baseball, so the tabbing system you have right now to distinguish pitchers and hitters is good, but expanding that concept to QB, RB, WR, WR/R, K, DEF would provide a good resource for all fantasy owners.

If you have any questions, email me. I'd love to help you out with this, and I could go on and on about where you could take this idea. The market for this type of site is just getting off the ground! My contact information is in my profile.

Great job. Curious where are you getting your raw data from?

Could be here: http://developer.yahoo.com/fantasysports/

@sparkygoblue Is anybody using this API? If so, have you ever used YQL? Since it integrates so many other languages like JSON, do you know how different it is from SQL?

Does anyone have any input on the cost that Pro has been set at or the pay structure of the website?

Pay structure should include a free 10 day trial. That way users will be able to see what kind of advanced stats and analysis that is provided. Through the free trial method, users will get a small sample of the site and develop a dependency of sorts on the site's analysis and find themselves needing it for the rest of the season!

There appears to be a lack of advertising on the site as well. Seeing that you work for Google, I'm assuming its not because AdSense wouldn't accept the request for ads, but a strategic move on your part. Nice job, it looks very clean and easy to trust. Having no ads at this phase in the site's development is a smart move, and as the site gets more web traffic it might be a smart idea to reevaluate.
