Manually create 2 datasets from specific season spans. Yes, I had to go back and put QBRs for every season… but it was totally worth it because here is the results of an ensemble model using boosted trees with 245 iterations: Topping .7 would be a HUGE advantage and I’ve tried adding in team and strength of schedule score but this model with just the added regular and post-season QBRs seems to work the best. If you feel strongly about them, you don’t want someone else to out-maneuver you for those picks. As you can see 2016 points is the best determinate for our rank in 2016.

I am creating a fantasy football database using excel that tracks the pertinent fantasy stats in my league for every player in the NFL.
