Is this a trick question? Just kidding. I noticed that some responses named soccer players but when I hear football, I think American football. My most favorite player all-time is probably Peyton Manning. The reason being is that when he signed a $100 million contract as a rookie, a reporter asked him what he planned to do with it and he responded "earn it." That is legendary to me and shows that he is a man of high moral character. I respect that and it a rarity in these days and times. Then he went on to do just that over the course of his career in Indianapolis.
My most favorite active player is probably Aaron Rogers. Not only is he a beast on the field and able to accomplish great things for a franchise that is synonymous for greatness with very little around him but I just love his swag. Confidence is incredibly important and when it's justified, you just have to love it.
