The first place to start is reading Fantasy Football for Smart People: A Guide to Winning at Daily Fantasy Sports by Jonathan Bales. Please click my affiliate link to get your free electronic copy. Please keep it mind the book may no longer be offered for free when you see this resource page. However, I consider it a must-read for anyone wanting to obtain a deeper level of understanding. The concepts may seem abstract initially but as you gain more experience you will develop a better understanding.
