The Buffalo Bills were back at it again on HBO's "Hard Knocks." It was the third episode of the NFL's offseason program for the team and there were many behind-the-scenes looks given to fans. Did you miss the bits from it? Maybe miss something?

Episode 3 of ‘Hard Knocks’ gave fans a deeper, more candid look at the Buffalo Bills' training camp, and James Cook signed his big contract extension.

The third episode of the five-part show airs tonight at 9 p.m. on HBO and Max, and stream live on Max. Running back James Cook signed a four-year extension since the second episode aired and Buffalo is coming off a 38-0 loss to the Chicago Bears in their second preseason game.
