The team is scheduled to meet with Oklahoma State quarterback Mason Rudolph in Indianapolis this week.
Rudolph has great size at 6-foot-5, 233 pounds and started three seasons for the Cowboys. He's considered by some outlets to be a Day 2 draft pick (second or third round).
General manager Kevin Colbert said this week Roethlisberger's presence provides security but doesn't change the Steelers' draft approach.
"If you draft a guy, then maybe in four years that kid is ready to play," Colbert said. "That does not dismiss Joshua Dobbs or Landry Jones with us either, because those guys are still young players as well. So you never dismiss any position because if you say you are not going to take a position and a player is available to you that you didn't project to be available at a certain pick, then you are going to make the pick regardless of the position."
Jones enters his third season as the full-time backup, and Dobbs will likely continue to develop as the No. 3. The Steelers could add competition to the quarterback room this spring.
Typically, the Steelers meet with around 30 prospects at the combine.
