Senior running back Jacob Schmidt said he isn't sure of Green's speed, but that the freshman's vision makes him a great runner.
"He just has a natural ability to find the hole; he's got great vision," Schmidt said. "I haven't seen his breakaway speed yet, but he's got a knack to find that hole, to jump cut, whatever he's got to do to get up and get positive yards."
"When we recruited him, he reminded us a lot of Tyrell Sutton," Fitzgerald said. "He's really thick in the lower body and runs well behind his pads. I just like the passion he plays with. He was excited out there and excited to play.
As a freshman, Green is obviously new to the speed of college football. However, he said he thinks he is beginning to make the transition.
"Coming in to the summer camp, summer school, everything was new to me," Green said. "The offense was different than what I ran in high school, it was hard for me to adjust. But being there the whole summer, coming in to the start of football season made everything a lot smoother, and I was more conditioned to get where I am now."
Despite feeling well-transitioned, Green stumbled on his first carry at Boston College, and admitted feeling nervous for the game.
"In my first carry, I stumbled a little bit, and showed my nervousness a little bit, Green said. "The second game I felt more comfortable, we had a great week of practice which helped me more to adjust."
The adjustments were obvious, both in the amount of carries, and what Green did with them. He had just one carry for three yards against BC, but had 14 carries for 70 yards and a touchdown against Eastern Illinois.
Green said the more touches and playing time he gets, the more his confidence will continue to grow.
"Coming into today's practice, I felt more confident," Green said. "I felt like I could do more, and the carries they gave me helped a lot."
Thus far, Fitzgerald said he is extremely pleased with the development of Green as a player.
"He's excited, he's got a ton of passion to play," Fitzgerald said. "He wants to be out there. He's competing his butt off, not only in the backfield but also from a standpoint of getting out there in the kicking game, so I'm really, really proud of him. He's doing a nice job."
One factor that may have been a major help to Green is the quarter system. While most freshmen are dealing with the transition of both football and school, Green has yet to step into the classroom. Instead, he's used the extra time to double his efforts on the field.
"It helps, especially with the playbook," he said. "With no homework to do or papers to write, it's a lot easier to just sit in your dorm, look up the plays, and know your assignments to get it down for the next practice."
Green's studying of the playbook paid off in a major way with his first collegiate touchdown against Eastern Illinois, a two-yard punch in.
"It felt great," Green said. "Before the game, I talked to my mom. We always pray that I have a good game, and no injuries. For that to happen, it was the last piece of the puzzle. I feel like I've been to college football now. I have a story to tell my kids in a couple years."
