Scott says it has been the most cohesive relationship of his career.
"We are absolutely on the same page in our thought process," Scott says, "And it really has made for a pretty good program."
McVay entrusted Scott, with a deep knowledge of the Rams' personnel, to help shape the roster and assist in hiring a strength coach.
Rath joined the Rams after eight seasons as a Miami Dolphins and Detroit Lions assistant.
"They've got a very deliberate plan," McVay says of Scott and Rath. "Very intentional, where everything that we try to do is geared toward helping our players be healthy mentally, physically, so that they can be at their best on Sundays."
Communication and trust, Scott and Rath say, are combined with analytics, wellness checks and recovery plans to keep players healthy.
Upon arrival at the team's Thousand Oaks facility every day, players answer a digital questionnaire -- similar to a short quiz -- about how their body feels.
"It only takes one minute," linebacker Mark Barron says, adding that it's an easy way to communicate about soreness and other issues. "Just little things like that where I feel like it helps them a lot and it helps us a lot."
Scott and Rath study the data, then implement the findings in the weight room and at practice, running back Todd Gurley says.
"If we feel bad, there ain't no reason having us out there going full speed when you really can't," Gurley says. "As long as we communicate with those guys, they've been doing a great job of taking care of us as far as our body, limiting the reps or doing different exercises or different lifts."
