The last two years, his team had a lead going into halftime against the cross town rival Petal Panthers, but wound up losing them both late in the game.
"We have been beating Petal at halftime, and we were 5-0 and winning at halftime against them the last few years," Nelson told GoldenEaglePride.com.
"We knew they were going to come out hard and we just got in the locker room and said, 'we have to stay focused, no talking.' They did come out hard but we were able to hold on and finally get over the hump against them. It was a big win for us."
With the win, Oak Grove moves to 6-0 and has taken control of the district.
"We are playing good football right now," Nelson added.
"We have one of the best coaches in the state, and we are playing together and as a team. We don't care who scores or who is getting the tackles. It is all about us winning as a team. Other than that, we are trying to stay humble.
"Coach says, "feet on the ground, mouth closed, and eyes on the prize." I've taken that and tried to apply it to myself, and that's just what I do."
The humble Nelson said he's just trying to do his part by leading the team by example.
"Yes sir, I'm a leader," he said. "We try to play hard and stay humble and just remain hungry. There is no magic formula, its just about us working hard and playing together."
He also is very grounded when asked about if he has a sense of urgency leading up to his senior season.
"It is still football," he said. "I'm not one of those guys who is real loud and saying we have to win because its my senior year.
"I know this might be some of our last year's to play football, and I know that every game is a blessing. Out of all my years, this is the best team I've ever been on. I'm excited about where we are and what we can do this season."
The Southern Miss commit remains fully locked with the Eagles.
"Football is football, and a couple of years ago USM was doing very well," he said. "Coach Monken is coming in and it is hard to come in and just turn it around in one year.
"We are rebuilding, but we will turn it around. Next year they'll be better, and the year after that they'll be even better. He's committed to turn it around."
Eleven true freshman have seen the field for the Eagles this season, and Nelson is excited about the opportunity to have a chance to compete right away.
"I'm excited about the chance to come in and get accustomed to college football and see what happens," he said. "I'd love to get to play and I'm coming in with the idea that if I work hard and get after I have a chance to contribute right away."
"I'll be coming in January and I can't wait to see what happens."
