For NFL players, the second week of the season can be a lot more comfortable than the first. You have film on your opponent, you know what to expect and you have that first game of the season out of the way.
That first contest of the year is important, especially with the new rules governing the offseason. Teams tend to make more mistakes in the opener than they do after getting into a rhythm. We saw some sloppy football in Week 1 this year. We should see less of it in Week 2.
At the same time, though, the second week of the season can be tense.
