Bubba Watson talks Masters, his hovercraft and Tiger's game

(CBS News) In the year since Bubba Watson hit a memorable shot from the trees at Augusta National Golf Course to secure a Masters victory, he has starred in his second "Golf Boys" rap video, bought Tiger Woods' home, and celebrated his son's first birthday. Looking ahead to the 2013 Masters Tournament, which begins April 11, Watson said despite his lack of tournament wins this year, "I'm playing pretty good."

"Obviously I haven't won yet," the golfer said Wednesday on "CBS This Morning." "Golf is so tough, the ball has to bounce your way, you have to make key putts."

Watson added that Woods -- back in top form after two tournament wins -- is "obviously the guy to beat" at Augusta National. "He's training the right way. He's putting really well, his life off the course is getting a lot better," Watson said,  adding, "He's healthy, his new swing is working."

Despite the pressure to beat Woods, Watson -- who taught himself the game and has never used a coach -- said he will remain self-coached. "[I'm] just kind of winging it out there," he joked. "I think I'm doing OK."

Watson said he is working on sharpening his "mental focus," explaining that while it "worked out right" at the Masters last year, he needs to remind himself that "golf is just a game." So for me, I've got to put that in perspective...I've got to be passionate about it and not get down when I hit a bad shot."

Turning to some of his recent hijinks off the course, Watson said the video in which he debuted his golf cart-hovercraft is an an effort "to bring fun to the game of golf." His rap group, "Golf Boys," features Watson alongside PGA Tour players Ben Crane, Rickie Fowler and Hunter Mahan, rapping in outlandish outfits.

"We wanted to bring light to the game of golf instead of being boring, so we changed it up," Watson said of the group.

At home, Watson is busy caring for his 1-year-old son Caleb, who he adopted right before the Masters Tournament last year. He said he and his wife bought Tiger Wood's suburban Orlando home "because of the community." "We love the security, the golf course, we love the family atmosphere there," Watson said.

He added, "Golf is great but family life is a lot better."
