SANTA CLARA, Calif. -- LaMichael James role with the San Francisco 49ers seems as secure as it has been all season.The team expressed confidence in James on Tuesday when it cut both Kyle Williams and Perrish Cox. They were the only other punt returners on the roster. James took over for Williams as the primary punt returner on Sunday.So, the team clearly believes James -- a backup running back who was a second-round pick last year -- can handle the job.
