The US open field is a little different this year than prior year's since there was no Qualifying Sectionals. They tried to adjust for in a fair fashion however, instead of simply taking all the best PGA tour players or highest players in the world ranking. Normally there are a number of amateurs and Korn Ferry tour players that get through via open qualifying, so they tried to match up to the past in terms of field composition. They took the top 10 players on the KFT and the top 7 players in the world amatuer rankings that were not already exempt.
There were about 13 players outside of the world top 50 (Between ranking 53 and 92) that got in this year, that normally would have had to open qualify which is no guarantee.

All that being said I can't truly value the champion this year, as they didn't actually have to beat me. Yes I am only an 11 handicap -- but I was a 14 handicap at the beginning of the year (after not playing that much in the previous 5 or 6 years). I am sure with the proper warning and foresight I could have worked hard and got my handicap down to below 1.4 over the course of a month. Then I think I would have got through qualifying fairly easily of course.
