So after looking through the list and looking at the leaderboard, you probably noticed a few discrepancies.
I have neither Darren Clarke nor Lucas Glover contending this weekend. The best chance those two have is that the weather calms down for them in the afternoon, and tears everyone else apart. Otherwise, these two just don't have what it takes for this weekend.
It's hard to see Glover holding on with only relative consistency this season. And Clarke has no majors, and this is the only major he has ever finished in the top five before.
Chad Campbell has tasted enough defeat at the hands of Tiger Woods, and it's not about to change with the weekend. He's been pretty irrelevant all season, and with the bright light of a T3 position on him, it's not going to make it any easier.
Davis Love III and Tom Lehman both have the same issue: they show up for two rounds, and then proceed to fall into a top 20 finish. Respectable, but certainly not contending.
And lastly Phil Mickelson. Although Lefty is capable of winning this weekend, he hasn't performed all that well in majors this year, and it's not like he has shown any dazzling change.
It looks like he will be waiting until the the PGA to regain a major.
