Steelers won’t make a coaching change. 3 coach changes since the ‘70s. Model of stability.
Brown and Bell are divas. Maybe Roethlisberger too. Most teams can only bear one diva. For me Brown skipping the last game of the season is unconscionable. At least Bell gave a seasons worth of pay for what he believes in.
Nevertheless the biggest issue with the Steelers is their aging defense. James Connor and Smith-Schuster are more than adequate replacements. I also suspect Roethlisberger will be back again.
You are likely correct with both Tomlin and Roethlisberger returning next season.
Regarding their defense, they've pretty much moved past their aging veterans. All of their starters are 29 years of age or younger.
