Russell Wilson officially earned the Pittsburgh Steelers as their starting quarterback on Wednesday. The former Denver Broncos and Seattle Seahawks quarterback has put together a prolific career, but struggled in Denver. After signing a massive deal following a trade from the Seahawks, Wilson was released by the Broncos after just two seasons there.

He drew the ire of Broncos fans and pundits, including former Broncos guard and now analyst Mark Schlereth. In the past, Schlereth has remained critical of Wilson, saying that his issues go far beyond just his play on the field, but his management of the locker room as a leader of men.

“Do I think they (the Steelers) might be able to compete for a playoff spot? Yeah, but the issue that is what got Russ out of Seattle and Denver,” Schlereth said on his podcast. “Russ isn’t willing to admit he isn’t good at stuff. He’s delusional. If you’re not willing to admit it, then you can’t fix it.”

Wilson had 26 touchdowns to just eight interceptions in Denver but boosted many of those stats in garbage time. The tape is ugly, but he did have a strong summer after returning from his calf injury, beating out Justin Fields in the competition.

Mike Tomlin and others around the team have remained complimentary of Wilson and his leadership. Offensive coordinator Arthur Smith has talked about how he intends to build the offense around Wilson’s strengths, which is his pre-snap processing and deep ball. The Steelers hope to build a strong running game and then build an explosive passing game down field off that.
