It was an incredible accomplishment for a guy that has only two other top-10s in all the majors combined, and his win brought about a few questions about the history of the Masters.
First, does Bubba get a second green jacket to go along with the one he received in 2012?
The answer, unfortunately, is no. Augusta National awards you one green jacket after your first win, and if you win any other Masters after that, you get that same jacket presented to you. The difference with the win is that you're allowed to take your green jacket home for an entire year, eventually returning it to Augusta National when the next Masters begins (they keep the jackets in house, and allow you to wear them when you're on the grounds).
So, someone like Jack Nicklaus doesn't have six different green jackets to pick from, just one jacket that accounts for all his wins at the opening major championship of the year (and you'll love this story about Nicklaus not even having his own green jacket until 1998).
And if Bubba is lucky enough to win the Masters in 2015, who will present him with the green jacket if he goes back-to-back?
That honor is bestowed on the chairman of Augusta National at the time, who would be Billy Payne if Bubba was able to pull off that incredible accomplishment.
As you see below, Tiger Woods received his 2002 Masters green jacket from Hootie Johnson, the chairman of Augusta National at the time, after his back-to-back win at Augusta.
