Romans play book was actually perfect for TT.
He he had some success in 2015.
In 2016 after the first 2 games, it was on Romans play calling, not his playbook that got him fired.
Lynn used the same play book with TT except he simplified it without the exotic plays.
So ya Lynn was technically a new coordinator in 2016 but it was the exact same playbook, as that was never the issue. Roman outsmarting himself was the issue.
So in his first 2 years TT has had the exact same playbook.
And his 3rd year he had a different one because his OC was promoted to a HC.
So i really don’t understand your reasoning.
Saying “TT has a different OC every year” to make TT look bad is skewed in many ways .
1. The playbook the first two years were exactly the same, as Roman outsmarting himself was the issue.
2. The reason there was a new one this year is because Lynn got promoted to be a head coach for the Chargers
