"I saw him like his first day of camp at Alabama," Jones said on Wednesday. "My brother was the strength coach there. So I was up talking to him and I was like, 'Who is this linebacker here?' I think (Henry) was 17 at the time and I was like, 'Goodness gracious.'"
The Titans drafted Henry in the second round of the NFL Draft. He joined the team this week.
"We've got a grown man and I'm happy he's on our team,'' Jones said. "He looks the same. He's a big guy."
Henry, last year's Heisman Trophy winner, racked up 2,219 yards and 28 touchdowns while guiding the Crimson Tide to the national championship.
In three seasons at Alabama, Henry ran for 3,591 yards and 42 touchdowns while averaging 87.6 yards per game.
He's listed at 6-foot-3, 247 pounds.
"I have been sizing up Henry, man. He's a big dude," tight end Delanie Walker said of Henry. "… He's a good dude. I'm just messing with him, giving him a hard time because I feel like he's going to be a monster for this team. I usually don't talk to the rookies until they make the team but he's one of the guys I think can help this team out...He's probably one of the biggest running backs I've seen."
Added cornerback Brice McCain: "Man, he's big. Straight ahead, man, he's going to be problem. He's a good addition to this team and I think he's really going to help us out."
Titans rookie linebacker Kevin Dodd played against Henry in his final college game.
Dodd, who's 6-5, 277 pounds, had three sacks while playing for Clemson in the national title game against the Crimson Tide.
Dodd said he's gotten friendly with Henry already, which came as a bit of a surprise to him.
"We have actually been working out together and got along pretty good. I didn't think we would at first because of the national championship game,'' Dodd said with a smile. "But we got along pretty good and I am glad he is my teammate."
That doesn't mean Dodd wants to tackle him. He remembers the title game, when Henry ran for 158 yards and three touchdowns, including a 50-yard scamper for a score.
"It was difficult, man," Dodd said. "He is a big back and you have to wrap that man up by his legs to take him down. He is a really good back and I am glad he's on my team."
