It's PGA Championship week! ESPN.com's Kevin Van Valkenburg (@kvanvalkenburg), who will be on site at Southern Hills, talks with Andy Johnson about all the major storylines heading into the second men's major of the year. From the challenges of the Perry Maxwell design to the players they think have the best chance to succeed, Andy and Kevin dive deep into all things PGA, including some suggested requirements for the club pros in the field this week. Note: This podcast was recorded before it was announced that Phil Mickelson had withdrawn from the PGA Championship.
