Tiger has always struggled to give credit to others. Back when he dominated the PGA Tour, Tiger often mentioned his winning attitude or his ability to focus under pressure during interviews.
When Tiger struggled, he often referred to the "we" in his golf game, as in; we mis-read the green, or we made a poor decision out there today.
One of the best things Michael Vick has done, was to credit the Philadelphia Eagles for helping him get his "football" legs back under him.
Vick is often quick to mention ex-Eagles quarterback Donovan McNabb and others for working to correct flaws in his game. This type of attitude has endeared him to both this teammates and the fans.
Tiger may not play a team sport, but he could easily credit those around him who have helped through this difficult time.
