Josh McDaniels is the leading candidate to become the next head coach of the San Francisco 49ers, but he has some reservations about the job.

McDaniels doesn't want to leave the New England Patriots for a job that doesn't work out, but he's serious enough about it that he has reportedly been reaching out to potential assistant coaches.

He also has four young children and a bad taste in his mouth after getting less than two years to turn things around in Denver when he took the head job in 2009.
