Jason Dufner will defend his title at the HP Byron Nelson Championship this week.
It's been a rough ride for Dufner in 2013, still in search of his first top 10. His win in 2012 was not without trend, as he shared eighth in 2012. We do have a little past history in the books when it comes to his defense of titles, as he shared 42nd in New Orleans three weeks ago. While he's a steady play in several formats, he's probably not one-and-done material quite yet.
