The build up to to the Super Bowl is when things get more and more surreal, and it only continues to do so. A day after John Harbaugh made an unexpected appearance in the Harbaugh family conference call on Thursday, and now Jim Harbaugh made his own unexpected call-in on Friday. Cam Inman has the details of Jim Harbaugh's call-in to John Madden's KCBS radio show, and it's pretty entertaining.

Coach Madden provided some advice to Coach Harbaugh, and while simple, it also made sense:

"I just know team that complains the most usually loses," Madden said. "The other thing I know is you haven't done anything yet. The team that celebrates having gotten there the most usually loses a little focus."

Although Coach Harbaugh is obviously plenty busy, it is not surprising that he would take a few minutes to talk with a coaching legend that has a Super Bowl victory on his resume. Harbaugh and his coaching staff all seem to constantly be on the watch for anything that will help them improve. Jim Harbaugh spent time talking with Bill Walsh at Stanford, and Greg Roman took some time to talk with Chris Ault about his use of the pistol.

Anybody is going to find themselves in trouble when they start thinking they have all the answers. Jim Harbaugh seems to recognize that he has plenty to learn.
