Kevin Cole, a data scientist at Pro Football Focus, joins me to talk football analytics. He describes his latest work in using Bayesian methods and player grades to evaluate NFL QBs. This allows him to assign a probability that Mitch Trubisky is better than Pat Mahomes and Deshaun Watson, no matter how small. We also discuss why QBs should not always minimize their interception rate. Finally, Kevin gives his thoughts on San Francisco, Green Bay, Cleveland and Baltimore.
