RENTON, Wash. -- Most of the talk about Seattle Seahawks rookie defensive lineman Frank Clark has been about off-the-field issues, but here’s what coach Pete Carroll had to say about Clark on the field in the three days of Seattle’s rookie minicamp.

“We moved Frank around all three days to try to gain some information on how he looks,” Carroll said. “He did fine. We played him at defensive end, we played him at Leo and we rushed him inside for the nickel stuff. He’s very quick and gets off the ball really well.”

Clark (6-foot-3, 275 pounds) had two plays on Friday that likely would have been sacks (there’s no tackling in minicamp) from the defensive end spot. He had another on Sunday while playing defensive tackle in a third-down situation.

“He showed some of the spark we hoped to see in the pass rush,” Carroll said. “He’s really fast and he’s really strong. He’s never going to be a 300-pound guy that’s going to load up, so we’re going to uncover the movement skills he has, the savvy, and what he feels comfortable doing. That’s all part of the process and there’s no rush. We’ve got plenty of time to figure that out.”
