“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.

Hard Knocks Episode 2 spotlights Damar Hamlin’s faith, James Cook’s contract standoff, and Joe Andreessen’s hometown rise.

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