Hours before kickoff Sunday, former Denver quarterback Russell Wilson chatted with former teammates and Broncos staffers on the Empower Field turf. After the Steelers polished off a 13-6 victory, the man who started in place of Wilson at quarterback was less diplomatic. Quarterback Justin Fields, who has guided Pittsburgh to 2-0 while Wilson deals with a calf injury, nodded to a long-time tradition of Pittsburgh coach Mike Tomlin in noting that Wilson and a pair of former Broncos — punter Corliss Waitman and receiver Brandon Johnson — got “petty game balls” after the game. “I think we all know Russ got did dirty last year,” Fields said.
