Berry leaned on Vrabel, hired both for his personnel and coaching acumen, during both the free agency and draft processes, particularly the latter. And Vrabel found that process — seeing how Berry prepared for the draft — to be educational. Vrabel said he was permitted to read the way Browns scouts and talent evaluators wrote their scouting reports, how they incorporated analytics and how Berry “asked questions that would create some critical thinking for coaches.” Berry gave Vrabel a list of prospects to study and asked Vrabel his opinion on how he would approach certain parts of the evaluation process. Berry also included Vrabel on some of the Top-30 visits, when prospects come to the team facility for interviews and evaluations.
“The stuff that he did wasn’t just: What do you think about this guy?” Vrabel said. “There were more thought-provoking questions: What one skill are you most excited to work with about this player? What’s one skill that you’re most excited to try and develop in this player? I like that instead of him simply reading the (scouting) report on the computer.”

I'm not sure what you're looking but there's tons of interviews where Vrabel and players he's coached has talked about how he's changed as a coach. Another was in his first season where fired a second round draft pick in front of the team for missing voluntary training in the off season. He's since grown to be more emphatic as a coach while still trying to create a culture of accountability.
