Dallas. Tennessee hasn't been very good at getting sacks or interceptions and the Colts have been good at avoiding those. The Titans had a huge game against the Colts in the first meeting...2 sacks, 2 INT, TD. Will they do that again? I like Dallas.
Feelings on Ben Roethlisberger? I could go Joe Flacco, or I could gamble on Ben and if he's a no go at the last minute, go Charlie Batch...
They're probably going to end up putting up around the same points anyways, above average points. So you may want to go with the 100% safe bet and start Flacco.
