One week he’s Devonta Freeman, the next Dalvin Cook. While he waits for his opportunity, Lions running back Tion Green’s job is to be someone different every week. An undrafted rookie out of Cincinnati, Green was one of the biggest surprises when the Lions’ announced their 53-man roster heading into the season. Six weeks and a dozen roster moves later, despite being a healthy scratch the first six games, he still has that job. He earned his spot with a solid training camp and electric preseason finale, where he racked up 150 yards from scrimmage and dazzled with a 74-yard touchdown off a screen pass. He’s kept the spot by fully committing himself to providing the first-team defense with the best impersonations he can on the scout team. “I pride myself on giving those guys a good look,” Green said. “If we have a running back that goes over 100 yards, I take that personally because I’m the scout team back. I want to give those guys the best possible look. If a guy does really well, it has to be because someone missed a key, or something. It won’t be because I didn’t physically prepare them.” Green fully immerses himself into the role. He studies his assignment’s tape and tendencies. While he’s perfecting the performance he’ll give on the practice field, he’s also looking to steal the best stuff and incorporate it into his own, developing game. “They’re all great backs,” Green said. “I’m a rookie, I look up to all these guys out there. Competing, trying to imitate them, it’s all a great experience.” On top of his scout team duties, the Lions keep Green on his toes within the scheme. Every so often the coaching staff will unexpectedly thrust him into a play, either as a running back and blocking back, to make sure he’s staying on top of his playbook.
