I feel like the narrative is wrong that the "bills got lucky".
You create your own luck. Zimmer wasnt' called up from the practice squad for no reason, and if he wasn't, maybe we would have lost. So that's not luck, thats skill. The coach saw a need to make changes, made some, called a guy up he thought would offer something to the team, the guy made plays. (Really he almost won us the KC game too, Zimmer would be a LEGEND right now even more so.)
