This weekly mailbag will address a series of Tennessee Titans questions that are stewing with the fan base. Saturday's topics include Marcus Mariota's development, DeMarco Murray versus Derrick Henry and more: We've got to be careful not to be overcome by recency bias. After Week 10, Titans fans were raving about how clutch Mariota was leading the Titans past the Bengals for a third comeback victory this season. Thursday, he turned in his worst game as a pro on his biggest stage. It was certainly troublesome to see that performance from a third-year quarterback who some thought could be a dark-horse candidate for MVP before the season began. There have been plenty of conversations at Titans headquarters about how to put Mariota in the best situation to succeed. Coach Mike Mularkey said they don't run anything Mariota isn't comfortable with. Mariota is one of the NFL's best QBs on play-action and he's had success running the no-huddle. It would benefit the Titans to put him in more of those situations. How great is Mariota's potential? That's a question for a different day. But this season, so far, he hasn't gotten closer to reaching it. My take is that the Titans' coaches and Mariota both are responsible for the quarterback's stall in development. But I'm not yet sold that he can't be successful in this scheme. My level of concern is about 4 on a scale from 1-10.
