My two cents worth.
Eugene is definitely versatile. I have seen him throw bullets up the gutter, all the way to playing 4th or 5th arrow. I have seen him throw 21 mph strike balls and I have seen him kill the speed to get a ball reaction. In this day and age the pros can not survive on tour with just one shot. I think a few things took place today; 1. As was said before, the shot he killed this week was not there. 2. He found absolutely nothing he liked in the warm up shots. 3. Due to the first two items, he had no sure plan to get to the hole. Where it appears he failed, is committing to a shot and then adjusting off that. I agree with legend, looks like his best bet was taking a bit of speed off and going up the boards. That would be more in his comfort zone or A game.

When he won 2 years ago he started way inside with a Vendetta Pearl, went 2-8-10, followed up by an 8-10, switched outside with the Element and ran off 6 in a row, most carrying the 6-7-10 started screaming and won the first match, then did the same thing in the final. That shows a little versatility, but nothing like a Duke or Voss. Prime example of how TV day is always different than match play/qualifying. Can have a shot all week and light them up, then get to the TV pair where 4 guys are on the same pair burning up a spot to use and his look is completely different. I havent watched the show yet, but when I do I will know more of how he did (or didnt do in this case).

NO SOUP FOR YOU!

Just to stir the pot a little...I can't help but note the fact nobody has mentioned that McCune beat a favorite of so many around here in order to make the show.  You almost got to see Traber

And, admittedly, the fact that those two went at it in the Round of 8 suggests that there was a good look during the week piping it to the pocket...
