NumberBall MLB Projection System by Jeff “JeffelJefe” Collins

Jeff “JeffelJefe” Collins of developed and refined this projection system over the last five years, using it as the foundation for what many refer to as the best year in DFS tournament history – 2018. He beat a 135 entry field to win $500k in the 2018 DraftKings Fantasy Baseball World Championship. Then he upped the ante by beating over 17,000 entries to win a million dollars in the FanDuel Fan Championship on the same day that he finished 2nd in their World Fantasy Football Championship (for another $200k). In case that wasn’t enough, he again finished 2nd (and 9th) in the FanDuel World Fantasy Basketball Championship ($200k+).

This system encapsulates his unique ability to find angles early and exploit them before the rest of the mainstream DFS community catches up. It includes all the basics of a good projections system like batter/pitcher matchups, ballparks, and Vegas impact as well as more advanced nuances based on custom proprietary stats that he has developed and refined every year.

Nobody in the industry can point to their results as proof of their process like JeffelJefe. And now you can be a part of that process.

Plus, it works with RotoGrinders’ LineupHQ, helping you build your ideal lineups for both cash games and GPPs.

Working in the Fantasy Sports industry since 2012, Jeff has witnessed Daily Fantasy Sports from every angle: business, content, and as a player. He’s been featured in the New York Times, the L.A. Times, numerous books including Dan Barbarisi’s “Dueling with Kings”, and numerous documentaries including Jason Baumgardner’s “Perfect Lineup”.

On the business side he worked with several startup operators in direct competition with FanDuel and DraftKings. Jeff brought a player’s perspective to the product side of things and was innovative with new features that you see the bigger sites now implementing today.

Content has always been a passion for him, so the opportunity to write for RotoGrinders early in his career was something to jump at. Jeff hosted popular shows for MLB, NBA, and NFL content and often focused on teaching a contrarian approach long before it was cool to do so.

Jeff’s run as a player has been capped off by what many refer to as the best year in DFS tournament history. A baseball live final win (DK), a football Million dollar score, and 2 2nd place finishes in FD live finals.
