The Patriots barely beat this Hawks team, btw. It's not the same scenario by any stretch of the imagination. The Cards are in the playoffs already, what do they care?
The talent doesn't just disappear/go away. But game-planning, and in-game playcalls need to be tailor-made for each and every game. And adjusted throughout each game. When the difference is this striking, it's obvious where the blame lies....
