2. Tennessee Titans
Ryan Tannehill just had the best year of his career so far. That’s why the Titans chose to reward him with a lucrative four-year, $118 million extension. However, that may prove to have been misguided. First of all, Tannehill’s excellent season was the exception to the rule.

His passer rating was 30 points higher than his career average. Can the 31-year-old produce those same numbers this year? The Titans extended Derrick Henry’s contract because he is such a key player for them. It’s a fair question if Tannehill would have earned his contract without the bruising runner.
