“Hard Knocks” has promised Bills Mafia and NFL fans an unprecedented look behind the curtain of the inner workings within Buffalo’s summer home at St. John Fisher University. To this point, it’s proven to be a success — no doubt helped by the presence of Allen.

The second episode of "Hard Knocks: Training Camp with the Buffalo Bills " has some intrigue. Running back James Cook decided not to practice last week as he seeks a new contract and the Bills had their first preseason game. Both topics could get airtime on Episode 2.

The “Hard Knocks” series returns Tuesday, August 5 with “Training Camp with the Buffalo Bills,” dropping 9 p.m. ET on HBO Max.
