I know that you know this, but a top 15 rank is just middle of the pack since there are only 32 teams in the NFL. The one year they were top 5 in offense, their defense was near the bottom of the league. The Titans are not doing it on purpose, they just can't put it all together. They are playing checkers when they should be playing chess. They have yet to show me that they have put the right decision makers in place to put a truly good offense and truly good defense on the field at the same time.
Also, I am sorry but until he actually puts more than one or two good games together you can't convince me that Levi's is a top level talent that can take a team past the first round of the playoffs.
