Here's the thing, the offense looked a lot more like previous iterations of the Titans offense but with the tweaks many of us called for and Tannehill looked a lot better.
Last week the offense was way too pass heavy and you can't say it was because they were too far behind and had to throw. They just chose to try to pass more last week for some reason.
The Titans had 34 rushes vs 24 passes this week compared to 22 rushes and 34 passes last week. Both were close games. Two very different strategies.
I think this shows that Tannehill is still capable of performing well, you can certainly win with him, but I'm not going to buy that he's a good fit for a pass first offense. Half his yards this week came on the two PA bombs, which were great throws, but are not examples of the more cerebral QB led offense I think they tried to run last week.
If Tannehill stays healthy and they play like this, then he's still in the tier of QB that you'd love to upgrade, but the opportunities to due so are few and far between. KC got lucky with Mahomes and were able to ditch Smith, the 49ers totally failed with Lance and then got lucky with Purdy to replace Garoppolo.
So far I don't think the Titans are likely to have found their next QB, but it's possible Levis or Willis take big steps. I think the Titans will be taking another swing at the position next year, and the only question is does Tannehill keep playing well enough that the Titans are basically what they have been in the Vrabel/Tannehill era... Good, but not great.
