"I would say Illinois and Cincinatti are the two schools I hear the most from right now," Armstrong said.
Last season as a junior he rushed for over 1,100 yards and scored 22 touchdowns.
Most schools are recruiting him to play "slot back," a hybrid position that could include plays out of the backfield or lined up as a wideout.
"I do that in high school now," he said. "I use my speed, ability to run and catch and my explosiveness."
Distance from home, Armstrong says, won't hurt a school's chances. But it has made taking visits difficult. With his senior season in full swing, taking a trip north to check out the two schools fighting for his commitment has been hard to schedule.
He knows what he's looking for -- he's just waiting to see for himself in person.
"A great school academic wise," Armstrong says, describing what will win his services. "A great environment where I can see myself living for the next four years and the team with the offense that looks best for me."
