The dynasty format elevates fantasy football by making the game more closely resemble the real world. There’s no reset button every season. Your decisions have lasting consequences and benefits that ripple out for years into the future. Furthermore, with the use of IDP positions, your fantasy player universe doubles to include all those exciting, underappreciated defensive players.
The key scorers in any good IDP league are the linebackers. Tackle-focused scoring leagues produce the most reliable results year to year. If you are thinking of starting a dynasty IDP league, please consider breaking it up into multiple positions: DL, LB & DB or take it one step further with every position: DT, DE, LB, CB & S.
