The Jets could leave Baltimore on Monday night knowing who will start at quarterback to begin the regular season.
"If there's such a thing as a special preseason game, I think this is it," Ryan told The Associated Press.
Rookie Mark Sanchez, who is believed to hold a slight lead over Kellen Clemens, will start for the first time in the game.
"It's going to be good for us," Sanchez said, "and obviously a great measuring stick against a tough defense."
