"You might be surprised to see the Titans here, given that Mariota is heading into the fifth and final year of his rookie deal and still hasn't quite answered the question of whether or not he's a franchise quarterback," Brandt wrote. "But this ranking is as much about the man behind Mariota as it is about the former No. 2 overall pick. Before we get into that, I have to say, I really like Mariota. He has tons of upside, excellent speed and top-notch athletic ability, and he's shown flashes of fulfilling his considerable potential. Ideally, the presence of Tannehill will help bring out the best in Mariota. But if Mariota should falter -- notably, he has yet to play a full 16-game season -- Tennessee could turn to the best backup quarterback in the NFL, a former first-round pick in his own right who showed in Miami he has what it takes to carry a team to the playoffs. (Though he missed the 2016 postseason with a torn ACL, Tannehill started 13 games for the Dolphins that season.) I can understand how some would find the uncertainty around Mariota off-putting. But the Titans are actually in the rare and quite enviable position of having two young, capable, starter-caliber options at the most important position in sports."
