His days are spent in airports and gyms. When he's not putting shots up or working on his floor game, he's sleeping on the next of what seems like endless airplane rides. Tuesday, he was headed to Indianapolis, Ind., his home for the next five weeks.
It won't be long now.
"Once I get there, they'll have a whole plan for all five weeks that I'll be there," Henry said. "Basically, I'll be working on just getting stronger, really. Working on every part of my game."
"They" is the staff of St. Vincent Sports Performance. Henry isn't the only draft-eligible player looking to better his game over the next month and a half in Indianapolis.
He'll be joined by some 15 other soon-to-be professional players, including Austin Rivers of Duke, a projected lottery pick. Marquis Teague of Kentucky will be there, too, as will Tanner Smith of Clemson.
Henry will arrive late Tuesday. On Wednesday, he starts his six-days-a-week workout regimen. From 7:30 a.m. until 6 p.m., he'll be lifting weights. And getting more shots up. And perfecting his floor game.
"This next month and a half, I'm going to be real anxious to see what happens. I'm more nervous than I've ever been," he said.
He's heard mid-to-late second round. There's even been some talk of the early second. "It just all depends on how I do when I get some workouts with some teams," he said.
He boosted his stock with a strong performance in the prestigious Portsmouth Invitational Tournament in Portsmouth, Va., in April.
The Portsmouth Invitational is one of the preeminent NBA pre-draft camps, with approximately 200 NBA representatives in attendance.
"That definitely helped, ‘cause there were a lot of representatives from the NBA there," Henry said. "They saw me personally. They saw how I played; they saw how my game fits in the NBA.
"I've got a versatile game. I can guard multiple positions. I'm an NBA wing, with how my game is. It translates to a perimeter wing."
Ole Miss ended its season with a first-round exit in the National Invitation Tournament and a 20-14 record. In the weeks and months that followed, Henry was in and out of Huntsville, Ala., where his agency is located.
A lot of his focus, as it was in his four years at Ole Miss, was and continues to be adding weight. He's been listed anywhere between 6-foot-9 and 6-11, but he never topped 210 pounds in his Ole Miss career. More weight could help him defensively, another point of emphasis.
"That's the main thing I'm working on: strength and putting some pounds on," he said. "It'll only help me at that level."
Sure, he thinks about Ole Miss. He spent four years in Oxford. But not a lot. Not right now, what with his future in the balance and work to be done.
He jokingly said he'll probably think more about his college days when he starts receiving and paying bills. There won't be a scholarship check coming in the mail each month.
However, when he does look back at his career, he'll remember the experiences, the good times he had.
No, Ole Miss never made the NCAA tournament in any of his four years. However, he did finish with 1,095 points, the 28th-most in school history. He was an All-SEC second team selection as a senior. He was only the second player in school history with 1,000 points and 100 blocks in his career.
"I'll try to catch a lot of games (next year)," he said. "All the pieces are there. Right now, looking at the conference as a whole, I don't see too many teams on paper that are better than them, other than Kentucky. They reload every year. Maybe Florida and Tennessee. Other than that, they're right up there."
It won't be long now.
