However, that's exactly what the 6-foot-4 1/2, 353-pounder is and it's precisely why schools like Tennessee are fighting for his signature on a National Letter of Intent.
The FOX Sports and Scout four-star prospect is the No. 26-rated defensive tackle in the country and as of Saturday the Volunteers are holding onto the top spot of his list of favorites.
The Brighton, Tenn., resident tripped east to see the Big Orange defeat South Alabama 31-24 in his first game witnessed at Neyland Stadium. He said the visit "helped" the Vols' chances.
"Just being in the stadium just looking around you just see a whole lot of orange and looking at the sideline and looking at the players they're all hype, looking at the fans," Mosley said. "That's what I really liked, just being in there."
Mosley says the orange-clad atmosphere lived up to the hype and he spoke with every Tennessee coach afterward. Their message was simple: "'Give me some good news. Make my day even better.' That's all they were talking about."
Tennessee ranks No. 2 in the FOX/Scout team recruiting rankings. Hopes are to see Mosley become verbal No. 26 on Friday. Having not visited Auburn and Georgia for a taste of gameday may delay a declaration.
"I'm still thinking. Right now it's still Oct. 4 but it may not be," said Mosley, rated by FOX Sports/Scout as the No. 6 player in the Volunteer State's senior class.
"It was great, my first game here, my first game this year," Mosley said. "So, I started off good coming in here, meet all the other recruits, just singing Rocky Top basically the whole time up here. I enjoyed it."
"I plan on coming back, hopefully," he said.
In a trip to the mid-state on Friday, Brighton impressed, taking down 2012 TSSAA Class 5A runner-up Columbia Central 35-0. For Week 6, the Cardinals host Munford.
