Is Steelers' Cam Heyward serious about NFL Week 1 holdout talk? Or posturing 'til the last minute?

Post-Gazette sports columnist Paul Zeise reacts to Cam Heyward's latest refusal to commit to playing in NFL Week 1 against the New York Jets amid a contract dispute with GM Omar Khan's front office. Is Heyward serious? Or is he just continuing to posture until kickoff in hopes of pressuring the team into a deal? Is whatever raise he could secure worth it in terms of fan backlash to his demands? And how would his absence affect T.J. Watt, Jalen Ramsey and the rest of the Steelers' defense? Paul tackles those questions, plus his thoughts on coach Mike Tomlin's weekly news conference, where he gave injury updates on players including Derrick Harmon and Nick Herbig.
