Thanks to Slyde for inspiration and my lack of anything productive to do this last Saturday, provided are links to roster maps for each team in the NL Central.
It's important to note that while the Reds 40-man roster appears set, other rosters are not so. I have simply taken the provided rosters within SBNation. Chicago only has 38 men listed in their current roster, while Houston and Pittsburgh have 42 each. Although they're not final rosters, it's still interesting to see which method of acquisition each team relies on most.
I apologize in advance for the less-than-stellar quality. I worked in Excel, and given the tools available (print, scan, convert, upload), this is what I was left with. If anyone has any advice for converting an Excel spreadsheet to an image, I'm all ears. Otherwise, I hope you enjoy (just try not to call too much attention to the new guy's apparent abundance of free time!)
