What I've noticed from the bits and pieces I've seen is his on course demeanor looks much better now, as if he's just enjoying playing golf. While acknowledging that his off course problems have affected his game over the last 10 years, it's hard not to wonder what might've been had he gotten his back sorted out properly years ago. Whether he wins another major or not, let's hope he remains fit and competitive for a few years yet because his return is a big shot in the arm for golf.
