"They always teased Terrence Miller about it last year, so I feel like I am going to take his position," Jones-Grigsby said.
"I think of it as a leadership role. These young guys are looking at me to make plays, but it is also showing them what they can do because they are our future."
Arizona has a wide open competition at running back and Jones-Grigsby is approaching it with determination.
"It means that there is going to be more competition," he said. "That is why I am a football player, because I love competition. At the end of the day, they are all my boys, but I am coming for that spot."
Jones-Grigsby recognizes the need to help the younger players out, but that doesn't mean he will let that take away from his own opportunities.
"It's a competition, but those are my boys," Jones-Grigsby said. "In the meeting room and out here, if they mess up I get on their butt and tell them they know what to do.
"They go and make it up the next play, but once I am on the field, I am going to get my reps and I want to play, so it is a competition."
With it being such an open competition, Jones-Grigsby feels he has something to show the coaching staff.
"I have heart," he said. "I have faced adversity and been here for five years. They were the only one that gave me an opportunity on special teams and I proved I can do that, so now I am hoping they can see this hard work is going to pay off on Saturdays.
"It shows that it takes time. You might not get the things you want, but if you keep working hard, success will come."
There are only a few more practices left in the spring and Jones-Grigsby is not taking anything for granted.
"These last few practices I have to be ready," he said. "The coaches tell me I am just getting to the main floor.
"There is the basement, main floor, and the roof. Hopefully I can get to the roof, so I can get in and play."
