Matt you are the only one I know that holds the Masters in lower esteem than either the US or British Open. Growing up I and most people I know held the British Open in lower regard at the time, now I hold the 3 as equals.
I grew up in St. Louis spending the 1970s in grade school and the 1980s in high school and college. I have always held the 2 Opens as above the Masters and the PGA Championship.
I made a strong arguement for Phil over Norman in Reply #48. Now having read additional postings since then, I want to argue against myself. Mickelson has 0 Open titles. Norman has 2 Open Championship wins. I reviewed my personal top 20 of all time list and realized Mickelson is the only one on my list without an Open win to his name (at least he does have a US Am). Even Weiskopf and Miller got some Open wins while competing against Nicklaus, Player, Trevino and Jacklin.
If I could win any tournament it would be the Open Championship. The US Open is my 1A choice. If A golfer is not from the US, I would think The Open Championship has to his most desired win. I can not fault any American choosing the US Open over The Open Championship (it is is National Open and one of the 2 premium titles in golf), but The Open Championship should still be choice #2.
Mickelson has never done much at The Open Championship, thus he hs reduced his odds of winning an Open title by 50%. Norman almost won some US Opens and did win his 2 Open Championships. Again, Palmer, Nicklaus, Trevino, Weiskopf, Miller, Crenshaw, Kite and Bill Rogers all won are came close to winning in The Open Championship and all usually made The Open Championship an important part of their season. Loof at Tony Lema; we will never know how good he could have become, but he does forever have the Open Championship as part of his history.
For some reason during the 1990s some US pros began placing The Open Championship as the 3rd or 4th (or less) most important tournament on their schedule. Curtis Strange at his height continued to play in the US the week before The Open (I know the tournament was in his home state of Virginia). Mickleson seems to also not place The Open Championship as a must win equal or close to the importance of winning a US Open. I do not buy that he hits the ball too high. Rather his high risk style should be slightly better suited to The Open Championship over the US Open. Palmer won 2 Open Championships with his single US Open win.
Therefore, until Mickleson wins at least 1 Open, he is not better than Norman in my book.
