You couldn't ask for more of a dichotomy when it came to players of the same position. Let's focus on Manning, though, when it comes to leadership. Leaders excel when they work within their talents. Manning's talents are basically two-fold: One, he throws the football very hard and very accurately, and two, he is very smart and is able to make decisions on the field as well as any coach on the sidelines. If a play needs to be changed, his strength is recognizing it and taking advantage of the situation given him.
If you're like me, you probably didn't find the game very interesting. Fumbles, penalties, and in the Broncos' case, when it was third down and seven or eight yards to go, Manning handed the ball off to a running back for a four yard gain. And then a punt. And it happened again. And again. And again. And each time the Bronco's punter would bury the Panthers way back in their own territory and allow their defense to do their job, which they did magnificently. And the Broncos won-which was the ultimate objective for the day.
I don't know Peyton Manning, but I'd say he has a pretty hefty ego. Can you blame him? He's the best at what he does and has been for quite awhile. Manning has been injured the last couple of years and his play has suffered. So, some of his strengths have, in fact, become weaknesses. Fixing weaknesses leads to being average. Manning didn't concentrate on fixing his weaknesses. He realized that he could no longer make the throws he used to, so instead, he used his strengths as a coach on the field, a game manager, so to speak, to lead his team to victory. He knew that his team's strength was their defense. Once they had the lead, he relied on the team's defense, their strength, instead of trying to fix his weakness, which was poor throws.
Remember, if you want to be an effective leader, recognize and work within your talents, and if you concentrate on fixing your weaknesses, you'll find average a lot sooner than you wanted to. Take it from an old football coach.
