NASHVILLE, Tenn. -- In plenty of situations at the Tennessee Titans' first rookie minicamp practice, second-round running back and Heisman Trophy winner Derrick Henry looked plenty capable.

Working with and against a group that included 20 tryout players who are unlikely to be in NFL training camps, he ran with authority in team periods, caught the ball well and drew unsurprisingly big praise from coach Mike Mularkey about Henry's pass protection recognition.

At 6-foot-3, Henry really stands out. But the way his 247 pounds are distributed, and with only a 2 on his uniform for now, he didn’t look as massive as I expected considering how his veteran teammates marveled at his size.

He was stumbling and uncertain in some individual drills. It’s not a big deal in one practice on one day, by any means. But high picks usually execute such things with grace, even right at the start.

“It’s different drills, you come out here to different things,” Henry said. “You’ve got to adjust. Once you get used to it, you get better at it. It’s the first day, so you try to do the best you can.”

Henry said he can make people miss just as well as he can run over a would-be tackler.

“It’s more of getting used to what we want from him drill-wise, and working on this he can get better at,” Mularkey said.

Like veterans who were excited about Henry earlier this week, rookies talked with near awe about the package the back brings to the Titans.

“He’s about as big as me,” said 6-2, 242-pound, seventh-round linebacker Aaron Wallace. “I haven’t gone against a back that big. When we put the pads on, it’ll be interesting.

“He looks like I’m looking in the mirror. It’s a lot. That’s a big back coming at you.”

Titans first-round pick Jack Conklin, an offensive tackle, said, "He looks like a D-end out there running the ball, but a little faster.”
