I can only say I've watched football since the 90s, but I don't think I've ever seen a coaching staff use so many of it's players in so many roles.
- The backup quarterback running Wildcat, Pistol, and option plays as a passer, runner, and receiver.
- Backup runningbacks and receivers regularly being rotated in and out.
- Tight ends lining up as fullbacks and receivers.
- Defensive linemen playing as fullbacks. 6th and 7th offensive linemen playing as tight ends.
- Star linebackers sitting out in favor of a 5th or 6th defensive back.
It's pretty incredible that the coaches get EVERYONE involved. I kind of thing the idea is good for getting "everyone involved" and keeps everyone happy/motivated. It's also really good because it gets those back-ups some valuable playing time. On other teams, players such as Daniel Kilgore probably wouldn't see the field unless it was a blowout or there was an injury. But by having him as a 6th or 7th linemen, he gets some live game experience for that one day when he may have to start.
