A whole new type of Fantasy Football League, called a Team Position League
A whole new type of Fantasy Football League, called a Team Position League. I tried this myself with an eight-member league for one year, and it worked flawlessly. Instead of having one QB, WR, RB, TE, and so on from a team, you would draft the team's entire position. For instance, if you drafted Patrick Mahomes as your QB, you would also be drafting all those other QBs on the Kansas City roster. In that way, if Mahomes was injured, you would receive his backup's points as well.
Each member of my league drafted two teams' QBs, four teams' RBs, four teams' WRs, two teams' TEs, two teams' Ks, and two teams' defenses. I even used a team's Offense as a different category. Every week, each league member would enter two of each of the WR and RB team positions, along with one each of the QB, TE, K, Team Defense, and Team Offense. It didn't matter if more than one member drafted the same team position, in that with so many combinations used each week, in the 16-week format and Championship rounds, not once did any member have the same positions used.
