I think I see this guy as luck/a miracle personified. I can't and won't say much about his talent, whether it's there or not, but take his faith and the crazy comebacks that the Broncos have been having and you've got something you've never seen in football before. Comebacks? Sure, they happen. At this frequency? Sure, in any sport. But with a religious twist? I can't remember the last athlete that was a proud Believer. At least not vocally and in the states.
Will it happen again next year? Sure, it could, but I feel like this "magic" theme of him and his team is really only interesting and valid for one season. Next season, maybe he can go for a rushing record for a TD, or maybe start passing a bit more as a QB. And, of course, have his team keep winning and competing from here on out.
Otherwise, this goes down as just this.."streak" where there was winning and no one could explain it other than with luck.
