"We're dealing with three new coaches on the (defensive) staff, so everything has to be detailed out," coach Marc Trestman said. "Descriptions, playbook issues, what other techniques we're going to use, fundamentals, clarity in our language. To have a language that is consistent. Mel's coaching, the defense, are Paul and Mel on the same page with the language and the terminology that we're going to use? Because Paul is coming from different places, so you'll sit in a meeting with Paul and Clint. It starts with stance and language. That's really where we are in the building of the playbook."
