Seahawks coach Pete Carroll, speaking at the NFL owners meetings, said his offensive coordinator, Jeremy Bates, had a "great" relationship with Marshall in Denver. Marshall, a restricted free agent, visited Seahawks headquarters early in free agency.
"We enjoyed the visit," Carroll told reporters at the NFL owners meetings. "We have a lot of information and background with him because of Jeremy. Jeremy Bates had a very good relationship with him in Denver."
Seahawks assistants Jedd Fisch and Pat McPherson were also in Denver with Marshall.
"Those guys all know him, so they give us unique insights, I think, to understanding how he could fit into the offense and what he could do in helping us," Carroll said.
Carroll's comments affirm the Seahawks' continued interest in Marshall even though there's no urgency to acquire him this far out from draft day.
