1.MAN UP: There is nothing that determines a team's toughness and physicality more than its ability to stop the run. It's caveman football, where simple blocking and tackling rule the day. Green Bay ranked 25th against the run last year, then allowed 207 rushing yards in its season opener. The Jets finished sixth in rushing offense last year, have upgraded their backfield, and ran for 212 yards in their opener. Can the Packers step up, or will their run defense be a season-long sieve?
