Football season is closing in and we have the return of Hard Knocks as proof. HBO's annual training camp docuseries is focusing on the reigning Super Bowl champions this year as the Seattle Seahawks take center stage. This is the first time since the very first Hard Knocks in 2001 that the show has focused on the reigning champions. There is no question that Witherspoon's deal is going to take up a lot of oxygen in the Hard Knocks edit.
