New book reveals why Rodgers-Favre relationship was strained from outset

Author Jeff Pearlman's book "Gunslinger: The Remarkable, Improbable, Iconic Life of Brett Favre," excerpted on Bleacher Report, includes a hilarious detail that may help explain why two Green Bay Packers quarterbacks had such a strained relationship.

Favre is known to have been unhappy when the Packers used a first-round pick on Aaron Rodgers, but perhaps it was their first in-person meeting that cemented Favre's distaste for the young passer who would eventually take his job:

Rodgers and Favre finally met on June 2, when the Packers came to town for a seven-practice organized team activity camp. Now merely a head coach (and a disgruntled one at that), Sherman allowed Favre to skip the workouts, but that didn’t mean he would not attend. In fact, that morning Favre was alone, sitting in the team cafeteria and reading a newspaper, when Rodgers saw him in person for the first time. The new quarterback approached the old quarterback and uttered what will forever go down as the worst introductory line in the history of professional sports.

“Good morning, grandpa!”

Silence.

Rodgers surely recognized the mistake as soon as the words emerged from his lips. But there was no taking it back. “Brett couldn’t believe that,” said Craig Nall, the backup quarterback. “It was like, ‘Grandpa? Who the hell are you?’”

Rodgers and Favre have since reconciled, of course. And perhaps Favre has a better appreciation for Rodgers' unique sense of humor - or Rodgers has a better idea of what jokes will land when around Favre.

Pearlman's book is available for pre-order and will be released Oct. 25.
