Henderson, a 5-foot-10, 225-pound fullback, is a "freak," in Downey's words.
Last summer, Henderson went to a SPARQ combine and bench pressed 185 pounds 35 times. Then, he rushed for more than 1,800 yards as a junior in an offense that produced three 1,000-yard rushers.
Still, even as an all-state performer on a team that advanced to the Class 3A semifinals, Henderson didn't draw much attention. In fact, his only offer is from Northwestern State.
That's starting to change, though. Henderson no longer remains off the national radar. His visit to Oklahoma's camp in June catapulted his stock, and while the offers haven't come just yet, the attention has.
Downey believes the offers will follow.
"He's going to end up getting as many offers as he wants," Downey says.
Despite a learning disability, Downey said Henderson carries a 3.1 grade-point average and recently took the ACT for the first time. He'll take it "three or four more times" and because of the Americans with Disabilities Act will get extra help.
"He's going to qualify," Downey said. "I feel sure about that."
But his disability limits the schools that Henderson can consider. Tulane, for instance, is out of the question. State schools, such as Louisiana Tech or Northwestern, or some of the BCS schools that Henderson has hopes for – like Oklahoma, Ole Miss or Auburn – can provide him the help he needs to achieve academically.
"Wherever he goes, they'll have to give him some aid," Downey said. "He can get that now with the state schools."
Henderson is "very explosive and very powerful," Downey said, and he is improving as a blocker to go along with his 4.65 speed and ability to run over defenders.
Downey believes he has the ability to be both a fullback and tailback on the next level and that whichever school takes a chance on Henderson is getting a great player.
"He's a freak physically. I've been coaching for 25 years, and I've never been around a kid that strong," Downey says. "There's no comparison. There's nobody close. He benches 470 pounds. There's nobody even in that class that I've been around."
