Discpline and execution is a constant issue with the Bills. This group needs an overhaul. Guys who know how to run routes and get separation is a must.
I would say that had more to do with the players not executing. Shakiir was open in the end zone. Bass missed the kick. Home field does have an advantage.
I doubt that the plan was to allow him to run free. It was a basic player doing one thing and the rest of the secondary was doing another. Poyer is the guilty party if you think the safety had coverage.
