The bills midseason hiccup started because of a freakin Thursday night game in New Jersey.
Like Richie said after that game, it throws a wrench in your schedule and messes up your routine. The away team really doesn't have much of a chance.
Then they follow it up with a tough saints team. A team that was on a winning streak and firing on all cylinders.
They then have to fly over all the way across to LA.
Imagine how tough that would be for an athlete, mentally and physically. You are 5-2 and have established a routine, a process if you will, and all the sudden have to deal with a short week, a mini bye, and then travel across the country. That is a hectic schedule.
That was the toughest part of the schedule, and unfortunately they fell flat. Can't blame them.
also, the bills have history of midseason collapses. 5-2 isn't that unfamiliar.
These reasons are why I think McDermott decided to make the QB switch. To wake and shake up the team. He has a good pulse of the locker room.
