I just ran the model on all of the playoff games up through the Superbowl, and the output I got was....interesting at best. I think the problem with this model is that the main factors it takes into accounts are the sets of PF/PA's and not an entire lot more than that other than ELO's and standard deviations. It pulls from ProFootballReference's websites to find the PF/PA. and to be honest, I think it might be flawed given that KC scored 14 points last week by not playing starters. I don't put any of my own bias into this output, but here it is.
Like I said, there is no way this happens, and I really don't think Baltimore is capable of winning the championship at this point. The model did have a great year but this is, as they call it, a scorching take.
If you'd like access to the model, just email me, I'd be happy to share :)
