I always hate when a "cool" saying gets used so much that it looses it's appeal. During this drawn-out presidential race, the term "fire in the belly" fell into that category. But, it is still applicable to presidential candidates and anyone else seeking whatever goal they're after.
American Captain Paul Azinger has always seemed like a fighter who has that fire. Most of his team will be decided for him, but he'll still have two picks. They need to have that burning to win.
After watching J.B. Holmes' enthusiastic reaction after he sank the winning putt in the first playoff hole against Phil Mickelson at the FBR Open, he seems to a have a lot of fire. If he keeps up that type of play, he should be a Captain's Pick if he doesn't make it in on points.
Same goes for Kenny Perry. He and Holmes are both Kentuckians and playing great golf. They both want to be a part of this Ryder Cup team, since it will be played at Valhalla Golf Club in Louisville.
Being a Kentuckian myself, I want to see them there, too. There, I've shown my bias.
