The last time Pittsburgh Steelers coach Mike Tomlin appeared in a Boston-area sports venue, he couldn't hide his frustration after his coaching staff dealt with headset interference in a loss to the New England Patriots.
In the 2015 opener, Steelers coaches heard the Patriots' radio broadcast in their headsets for the majority of the first half. The Patriots won 28-21. A frustrated Tomlin said in the postgame news conference "that's always the case" in Gillette Stadium. An NFL football operations rep called the interference "intermittent."
Both teams made the playoffs last season and will play each other in Week 7 at Heinz Field.
You can find Tomlin at the ballpark during the spring and summer months. He visits PNC Park fairly often to catch Pittsburgh Pirates games.
