I've been on teams when they believe in one another & no matter if they're losing, they believe they can win. It's powerful, believe me. And a team like that doesn't come together very often. When everyone has each others back & believes the guy next to him does too as well as trusting he will do his job... GREAT THINGS happen. It all starts with the head coach & his coaches...
Yeah, the best teams I ever played on weren't dominant, they were the teams that would bail each other out of trouble.
D gives up an easy TD or goal? O gets it back. O turns the ball over? D forces a punt or turnover. Those were my favorite teams to play for.
