Sports Illustrated: Jim Harbaugh, 49ers Aggressively Pursued Peyton Manning in 2012

Former MMQB Editor-in-Chief Peter King shares the relatively unknown story of Jim Harbaugh's pursuit of Peyton Manning in 2012.

Even though the San Francisco 49ers were coming off a 13-3 season, head coach Jim Harbaugh was aggressive in pursuing Peyton Manning during his free agency in the spring of 2012. Harbaugh even watched Manning work out at Duke University in a disguise -- a Duke hoodie bought from the campus book store -- in order to maintain some secrecy.
