The Titans announced Tuesday that QB Ryan Tannehill will start Sunday's game against the Chargers. The move doesn't come as a surprise after Marcus Mariota was benched in the Week 6 loss at Denver. But it's a significant shift away from the "franchise" QB. Mariota's in the final year (the option year) of his rookie contract and seems almost certainly done with Tennessee after this season. Tannehill is on just a 1-year deal and already 31. If the Titans can get competent QB play, they have enough pass-catching talent to deliver at least usable fantasy value around the offense -- including under center. We wouldn't consider Tannehill outside of DFS and 2-QB leagues in his first start.
