Well folks, preseason games have come and gone, and we are inching ever closer to Week 1 of the NFL regular season. Even though these exhibition games don’t count toward teams’ win-loss records, they are far from meaningless for fantasy football managers. New coaches, new players, and a new year present a great deal of uncertainty for IDP rosters, but preseason games can give us a glimpse of what to expect for the next 18 weeks. Keeping a close eye on which players are playing, and perhaps more importantly who isn’t playing in preseason games allows us the opportunity to piece together how defensive coordinators plan to use our IDPs and helps us deduce just how large of a role they’ll have.

“But wait, I haven’t been watching these glorified practices! What am I supposed to do now?!” Don’t worry, my friend, I knew you’d be busy enjoying the last few weeks of summer, so I went ahead and paid all the attention for you!
