A coworker asked me to join a company fantasy league and his set up is a bit odd. It is a 12 team .5 ppr league, with 2 flexes instead of 2 RBs, with 2 IDPs included. I have only played 10 man standard so the ppr aspect and IDPs are new to me. I have a pretty good handle on what PPR looks like, but am not sure about IDPs and what a draft strategy for them would be or what that even looks like. Anyone have any advice for me?
