It is hard to believe that Mickelson has still not taken to Twitter, while golf's other superstars have embraced it. Always one of the most vocal players on tour, Lefty would be a perfect fit for Twitter and its 24/7 audience. He has a history of shaking things up and has recently spoken out against the proposed ban on anchored putting strokes. Mickelson is also a sports nut, famously winning over half a million dollars by placing a $20,000 preseason bet on the Baltimore Ravens to win the 2001 Super Bowl. We'd like to hear who he bet on this year.
