This is an excellent read about the connection between Frazier and Harbaugh but also about how Frazier's past experiences prepared him to be a head coach in the NFL:
After the San Francisco 49ers won the NFC Championship Game last Sunday, Vikings coach Leslie Frazier texted his congratulations to 49ers coach Jim Harbaugh.
Harbaugh texted right back.
"He said, 'You congratulate me, but I want to congratulate you,'" Frazier said last week from Alabama, where he's scouting at the Senior Bowl. "Jim said, 'I want you to know how much me and my staff and our players respect you and the way your team plays, and the way your staff coaches.'
"That meant a lot to me. That was a big win for us to beat them this season.''
