Something else I thought of last night... It may mean absolutely nothing.
But I saw a quote from Coach McDermott that said, basically "I'm going to get a bite to eat and change clothes and get to work on Dallas". Conveniently, the Bills were at home in an early time slot yesterday, where the coaching staff could literally go down to their offices after the postgame press conferences and get to work with it being a short week. Dallas had to play on the road, in the later time slot. Which means that after their 4 hour flight back home, it was probably 2:00 am. Bills coaching staff already had a head start on them.
Again, it could mean absolutely nothing. But i feel like every minute counts in these short weeks.
