Pittsburgh Steelers head coach Mike Tomlin says "all options are on the table" as he searches for the franchise's next quarterback with Ben Roethlisberger's expected exit.

Veteran two-time Super Bowl winner Roethlisberger is yet to fully declare his intentions but it is widely anticipated he will depart the Steelers.

Mason Rudolph and 2019 first round pick Dwayne Haskins were QBs on the Steelers 2021 roster while they could explore their trade or free agency options with Russell Wilson and Jameis Winston potentially available.

"All options are on the table," Tomlin told reporters on Tuesday. "I enjoy working with [general manager] Kevin [Colbert] this time of year because we speak plain English.

"We have to improve our football team. There's two major ways you do it. You do it to free agency, and you do it through the draft.

"We have to look at what's available to us in the draft positionally. And we have to look at what's available to us, potentially, in free agency, positionally, and then we kind of bring those two discussions together.

"It kind of gives us a path in which to go about addressing our needs."

Tomlin added: "Quarterback mobility is valued not only by me but everyone. It's just a component of today's game and increasingly so."

Contracted QB Rudolph and Haskins, who joined the Steelers from Washington in 2021, were used sparingly in 2021 and would need to make a major step-up to be starters.

"Mason and Dwayne have had their moments, but they'll have to prove that," Tomlin said. "And not only in the team development process but through playing itself.

"They're guys that start that I wouldn't characterize as every-day starters. And so they'll be given an opportunity to establish themselves, and there's going to be competition. There always is.

"I think that both guys have positioned themselves to fight that fight with what they've done from a work standpoint and a professionalism standpoint in 2021."
