Orientation is underway at Texans headquarters as head coach Bill O'Brien welcomes his first crop of NFL rookies to the practice field for the first of three rookie minicamps.
"It's an eye-opener," O'Brien said. "It's a different level of competition."
At the head of the class was defensive end JD Clowney, who was under the helmet for the first time since becoming the top overall pick.
"We don't know what we think we know, basically," Clowney said. "We're just learning. It's really just trying to learn with the playbook, go with the team and listen to coach O'Brien."
With seven of the team's 10 draft picks signed to contracts before taking the field, the focus was solely on football Friday.
"The whole draft process is behind us," rookie quarterback Tom Savage said. "Now we're just here to work and find a job."
