No. Not everyone uses an optimizer. However, each time you deposit more money in DraftKings or FanDuel remember every player using one is taking advantage of our stacks, correlations, projections and more. Sounds intimidating, but our optimizer will level the playing field. It's not possible to calculate the trillions upon trillions of combinations, stacks, correlations, etc...consistently by manually entering lineups. So as much as we appreciate the players that choose to go it alone, we would rather you join our team, leverage your background, ideas, and insight and use our optimizer to win.
