How does Pete Carroll's extension in Seattle affect Jim Harbaugh's status with the San Francisco 49ers?Not much.Carroll was going into his final season and has won a Super Bowl. Giving him an extension was a non-brainer for Seattle ownership. Harbaugh has two seasons left on his deal and has not won a Super Bowl, so it's a bit more complicated.It has been well documented that the 49ers want to give Harbaugh a contract and will continue to work toward one.
