It takes a special kind of stamina to chase down Steelers quarterback Justin Fields an entire game. That’s why Zach Allen is paid the big bucks. Allen was in Fields’ face from the start of Denver’s matchup against Pittsburgh last week. But it wasn’t until the two-minute mark of the second quarter that Allen took down the speedy signal caller, maneuvering past a pair of offensive linemen before striking Fields on his blind side. Through two games, Allen has been one of the best pass rushers in the league.
