The Seattle Seahawks' Pete Carroll has rugby-style tackling, Mike Tomlin has robots.

But both NFL coaches are active in promoting player safety, two prominent voices on a subject who's importance shouldn't go overlooked.

As the Pittsburgh Steelers introduced their experimentation with robotic tackling dummies as a way to simulate contact in practice, Tomlin told Steelers.com the mechanism helps promote "the hand-to-hand or man-to-man combat associated with that teaching."

This isn't a new message from Tomlin, who is a big proponent of form tackling as a way to lessen risk. That process is challenging in an inherently violent sport, but Tomlin hopes coaches serve as "gatekeepers," as he outlined in a 40-minute speech to the Western Pennsylvania Interscholastic Athletic League. The WPIAL is composed of athletic directors, coaches and trainers in the area.

According to USA Today, here is part of that speech from Tomlin, who floated the idea of incentivizing players with a 'Form Tackle of the Week' or 'Block of the Week.'

"We're gatekeepers, very impactful on the young people we deal with, and so we have to be very mindful of the words we use, and those words have to be consistent. It's our words and our actions, because the young people are watching it all, and so it goes beyond establishing these cute catchphrases that the guys are going to remember. Think about ways you can incentivize that, think about ways you can reinforce it with action.

"Player safety and concussions and head injuries are our generation's opportunity to not only safeguard the game but also to be active participants in the evolution of the game. This is our generation's cause as it relates to football."

< "I'm never going to tell you guys how to run your programs. A guy walking around all week with a big sledgehammer -- that's great, that's a beautiful thing, because it encourages the attitude of hard and fair play that we desire. But be mindful of the criteria for those incentive-based programs, and what a great opportunity to reinforce the evolution of this game and the culture change by being inclusive in those incentive programs with things that back up the catchphrases and the teachings we use in this area."

The Steelers have not committed to using the moving dummies long term, and if they do, 2017 would be the earliest for implementation. But the Steelers and their head coach are seem willing to be active participants in the safety discussion.
