For Hemphill, the recruiting process has sped up quickly in a short amount of time.
"I really couldn't tell you too much about any of the schools on my list right now," Hemphill said. "I'm going to do a lot of research. It started off with me just having two offers, and all of a sudden, they just started coming in."
Irish assistant Kerry Cooks was in Texas on Thursday, and he stopped by Manvell to take in a spring workout.
"After practice is when I found out I had the offer," Hemphill said. "I was getting a lot of stuff in the mail from them, so I knew the interest was there. I don't really know much about Notre Dame, other than they wear gold helmets."
Though Hemphill doesn't have any favorites, he named Maryland, Texas, and Texas A&M as the programs he's established the strongest relationship with thus far.
"I want to play in a pro-style offense where the ball gets thrown a lot," Manvell said. "I'm also going to pay attention to what quarterback that schools recruit for my class."
Manvell said location won't play a factor in his decision, as he's "not one to get homesick."
As a sophomore in 2013, Hemphill had 587 yards and scored 10 touchdowns to earn First Team 22-5A All-District honors.
"I spread the field well and go up for jump balls," Manvell said. "I have a 4.4 in the forty-yard dash, and I have a 34-inch vertical. I catch with my hands and make plays."
Hemphill also runs track, competing in the 4x2 and 4x4 relays for Manvell.
