"We're hoping that Dee picks up where he left off," Thurman said on a conference call on Tuesday. "If he does, sky's the limit."
Milliner, in his rookie season, played in 12 games, with three interceptions. He also had 45 tackles.
"We believe in him," Thurman said.
Thurman also said that he is comfortable with the team's cornerback position, but he said they'll find out if they upgraded in the future.
"We have guys that can play," he said.
