Double headers

My league decided to do double headers this year were everybody would face two opponents per week rather than one. I’m curious what are the advantages and disadvantages of doing this?

Never heard of it but sounds fun! I don’t think it changes your lineup strategy much because you still want to just play your best players that you can. Not try to “cancel out points” as a strategy. Aka playing Meredith over Cobb because the other guy has Drew Brees. Just play the best matchups!
