Morris was the Seattle Seahawks primary kickoff returner between 2002 and 2004. He was consistent though unspectacular and was supplanted by Josh Scobey for kick returning duties in 2005. Morris saw limited action behind Shaun Alexander, the 2005 MVP, though his contributions did not go unnoticed by teammates. Alexander told the "Seattle Times" on August 17, 2006 that Morris could start for at least ten different teams in the NFL and could produce a thousand rushing yards and eight or nine touchdowns if given the opportunity.
