Not necessarily. The Titans have a history of acting like they are doing a thorough search and then just promoting from within. Want to give the fans the illusion it was really a search.
I get why you're saying that, but he's done it with the defense. You'd think his hubris wouldn't want someone encroaching on his "specialty", but his first choice at coordinator was Pees. You can say Shane Bowen was a project, but after one season he brought in Schwartz. Then also Jim Haslett. On the offensive side, which is not his specialty, they've all been projects. I think his top choice was Ryan Day who had been at OSU I think just one year. Seems backwards.
Lol I get it. But look it at more like, Andrew Luck's OC in college and Pros, and Justin Herbert's QB coach for Rookie of the Year. He has no connection to Vrabel. They were on the team at different times. Working for the Texans may just have been a paycheck. Although, he did make Davis Mills look good at times.
