Defenses go extremely vanilla in preseason so if you can get a backup qb with experience you could look to go over in those games. I'm thinking bears, colts, etc. Colts won't play Ryan but ellinger is a preseason mvp. Bears will play fields some and simien will/ should do well.
The steelers and Seahawks strike me as possible over teams in preseason. Backups with experience and coaches who take preseason a tad more serious than most
