Two of the three Rhetorical appeals are used: logos and ethos. Logos is used most prominently throughout this speech, he tells his team that they will not lose and will be a winning team. He uses ethos by mentioning to his team that "I’ve never been a losing coach, and I don’t intend to start here." (Vince Lombardi). This is showing his experience and why he will be a great coach. His use of logos was clearly effective seeing that the Packers went on to win their first game against the Chicago Bears.
The only other appeal that was left out was pathos, this may have been left out so he would not be seen as soft, or as a pushover of a coach.
His diction throughout the speech is what persuaded the team the most. His repeated use of the statement "We will..." gave his team a belief that they would complete whatever he said. This made his team believe in his statements from that first game onward.
