Since then, the 6-foot, 180-pound receiver from Leesburg, Fla., has never wavered from his pledge. With signing day less than a month away, Jefferson says other schools have stayed in contact with him, but he politely turns them away.
"Central Florida calls me to see how I'm doing," he said. "Some others as well, but they know I'm solid (to Boise State), and I keep telling them that."
The standout athlete who boasts 4.45 speed picked the Broncos over 12 other FBS offers, including Cincinnati, Duke, Iowa, Iowa State, Oregon State, South Florida and, of course, Central Florida. To prepare for his time on The Blue, Jefferson is putting in plenty of work in the warm Florida sun.
"I've been in the weight room, running routes, doing field work and just trying to get ready," he said.
"I keep in contact with a lot of the incoming recruits," he said. "We're excited to get up there and keep the tradition going."
Jefferson watched every Boise State game this year, and, like the team's 12 other verbal commitments and growing fan base, he enjoyed the Broncos' Fiesta Bowl win over Arizona.
"It was great. It was exciting," he said. "I haven't missed a game all season."
On the morning of February 4, National Signing Day, Jefferson will scribble his name on his Letter of Intent and fax it across the country to the Boise State football offices.
"I'm going to sign at (my high) school. That way all my friends can come," he said. "Then over the weekend I will have a get-together for my family and friends to celebrate."
