Titans will still probably squeak into the playoffs. Need a serious rebuild on offense. The defense still has solid pieces. Need to prioritize resigning Jeff Simmons. Will get Landry back next season.
But the offebsive overhaul might have to start with the value you'd get from trading Henry. Prioritize offensive line rebuild. If you can rebuild the line, draft some talented young WRs and RB, then sign a veteran QB like Rodgers you might have another run in the next two years simply because of the defense. Otherwise you clean house and trade errbody.
