But there is one big similarity: The ability to avoid pressure.
When the Steelers and Cowboys meet Sunday afternoon at Cowboys Stadium, how the two avoid pressure will be interesting to watch. Romo spins away from defenders before they get to him and has the ability to break free of tacklers.
Roethlisberger doesn't do much spinning and is a bigger target at 6-foot-5, 241 pounds, but his strength allows him to get away from defenders who try to bring him down.
"Luck," joked Roethlisberger when asked about how he escapes pressure. "It's a little bit of everything. It's having the vision, just having what you hear quarterbacks talk about that clock. It's a sense in your head, something's got to be breaking down or something has to be going on. It's just something I don't think you can practice. It's something you have."
