Tiger is amazing. I don't know how any reasonable person can look at what he has done on the golf course and call him erratic and overrated. He has been consistently dominant for his entire career:
Career achievements
Main article: List of career achievements by Tiger Woods
As of August 2007, Woods has won 59 official money PGA Tour events, has 20 other individual professional titles, owns two team titles in the two-man WGC-World Cup, and leads the FedEx Cup points standings. He has successfully defended a title 20 times on the PGA Tour, has finished runner-up 22 times, third place 17 times, and has won 28% (59 out of 213) of his professional starts on the PGA Tour. He has a 29-6 record when leading after 36 holes in Tour events, and a 40–3 record when leading after 54 holes. Woods is 13-0 when going into the final round of major with at least a share of the lead, and he has never lost any tournament when leading by more than one shot after 54 holes. He has been heralded as "the greatest closer in history" by multiple golf experts.[56][57][58] He owns the lowest career scoring average and the most career earnings of any player in PGA Tour history. He has been the PGA Tour Money Winner seven times, trailing Jack Nicklaus by one, the PGA Player of the Year a record eight times, the Vardon Trophy winner a record six times, and the Byron Nelson Award winner a record seven times. Woods is one of five players (along with Gene Sarazen, Ben Hogan, Jack Nicklaus, and Gary Player) to have won all four professional major championships in his career, known as the "Career Grand Slam", and was the youngest to do so. Bobby Jones won all four of what were in his era considered major championships. Woods's win at the 2005 Open Championship made him only the second golfer (after Nicklaus) to have won all four majors more than once. Woods holds at least a share of the scoring record in relation to par in all four majors, and also holds the margin of victory record in two majors, The Masters and the U.S. Open. With his victory at the 2006 WGC-American Express Championship, he became the first player in PGA Tour history to win at least eight times in three seasons. His victory in the Buick Invitational in January 2007 placed him 2nd for the longest PGA Tour win streak at 7 straight. Only Byron Nelson's streak of 11 wins in 1945 is longer. At the 2003 Tour Championship, Woods set the all-time record for most consecutive cuts, starting in 1998, with 114 (passing Byron Nelson's previous record of 113) and extended this mark to 142 before it ended on May 13, 2005 at the EDS Byron Nelson Championship. Many consider this to be one of the most remarkable golf accomplishments of all time, given the margin by which he broke the old record (and against stronger fields in terms of depth than those in Nelson's day) and given that during the streak, the next longest streak by any other player was usually only in the 10s or 20s.[59][60][61][62]
