About RosterResource

Since I was a kid, I’ve always maintained some form of roster tracking as I’m doing here. Now I’m just sharing my notes with you in a much more organized and easier-to-read format. 

MLBDepthCharts was created and launched in February 2009. The goal was to become a valuable resource for baseball fans by offering up-to-the-minute roster projections in the offseason and an accurate look at a team’s organizational depth throughout the entire year.

In July 2011, MLBDepthCharts was named to SI.com’s inaugural Twitter 100, a list honoring the most essential twitter feeds in the sports world. The site has also received Twitter shout-outs from ESPN’s Senior Fantasy Analyst Matthew Berry, former Dodgers GM Dan Evans, and Hall of Fame baseball reporter Peter Gammons. In addition, the site has been referenced in numerous articles on websites that include FanGraphs, Baseball-Reference, Grantland, and Sports Illustrated’s February 28, 2011 cover story titled ‘Brave New World’. A 2013 episode of MLB Network’s “Clubhouse Confidential”also referenced MLBDC’s “How Assembled” charts.  

With the help of some fellow “roster geeks”, I expanded the operation in September 2014 to include several other major sports to form RosterResource.com.

My writing has been featured at ESPN, MLBTradeRumorsBaseball Prospectus, USA Today and Bleacher Report. I’ve also appeared as a guest on various sports radio shows and podcasts, most notably CBSSports.com’s Fantasy Baseball 360 and as an in-studio guest at ESPN Headquarters in Bristol, Connecticut for the Fantasy Focus Podcast

The site is operated from my hometown of San Diego, CA, where I live with my son and daughter.

As has always been the case since the inception of MLBDepthCharts, RosterResource relies heavily on readers to put together content that is accurate and not outdated. Please contact me to provide feedback, suggestions, arguments or to point out mistakes. 

Hope you enjoy!
