York has acknowledged what he's termed a successful creative friction between the duo. The partnership between Harbaugh and Baalke has been wildly successful since they joined forces in 2011. The 49ers, who had 39 wins from 2004-10, are 41-14-1 over the past three seasons, including playoff games. Harbaugh is the only coach since the AFL-NFL merger in 1970 to lead his team to a conference championship in each of his first three seasons.
