The 6-foot-2, 185-pounder held down signal-caller duties at Harrison (Ga.) High School for coach Matt Dickmann last fall and is taking the winter seriously, matching up against top talent in all-star events.
Nunez competed in the Rising Seniors game in Georgia with other top junior prospects. He finished 5-for-8 passing for 78 yards.
"A lot of talent," Nunez told InsideTennessee. "It was an honor to play with all the players from around Georgia, just meet them and be friends with them and see who was going to which school and things like that.
Not long after that event, the Scout four-star made his way south to take part in the Under Armour Combine at Tropicana Field, throwing to wideouts like five-star George Campbell.
Several FBS programs are already sold on Nunez's ability, including Tennessee. He came to Knoxville for an unofficial visit to see the Volunteers take on Vanderbilt at Neyland Stadium in November.
"I like it a lot and what they're doing with the offense," Nunez said. "Joshua Dobbs stepping in for Justin Worley…he did a pretty good job. It was a rough game, but I like the atmosphere and the fans."
Tennessee offensive coordinator Mike Bajakian and wide receivers coach Zach Azzanni stay in touch.
"We talk a few (times) each week and stuff like that," said the No. 222 player in the 2015 class. "I talk to coach Z, the wide receivers coach up there, too. They're wanting me to come up there on some junior day and talk to them."
"I mean there's a lot of good receivers everywhere that are going to different colleges. I just keep my options open," Nunez said.
"It was a good offer for me to have because I fit their offense," Nunez said of the Aggies. "If I go in after him, it'd be a good opportunity for me to sign."
