Is this the best we'll ever see Jordan Spieth play?

Now that Jordan Spieth has put the finishing touches on a historic season that included two majors, five wins and the FedEx Cup, the question is if he can replicate that kind of season again.

We look at some of the headwinds Spieth will face in trying to keep up winning as he has been this year. While he's an above average length player, he relies on putting to score, which is a skill that erodes more quickly than distance. Also, we wonder if Spieth can maintain the same level of mental toughness he's showed this year for another decade or more.
