Old And Desperate Beats Young And Entitled Again

Hello. Congrats to Woody Austin for winning the St Jude with a closing round 62. Austin salvages his year, and possibly his career, with the victory. Austin was probably the least likely pick to win this tournament. Now he has a two-year PGA exemption.
Austin's win came at the expense of Adam Scott, who had a 3 shot lead heading into Sunday. However, Scott ballooned to finish 4th. He now seems to be following in his mentor Greg Norman's shoes in not being able to close out tournaments.
Is it possible that the 20-somethings on the PGA Tour are not as driven as they could be? They know they'll keep their cards, and they know they're not going to challenge Tiger, so they cruise through life, keeping their fans and groupies happy?
It seems like now you can look at a leaderboard and predict that the 40-somethings are going to come through, while the 20-somethings fade. There's just so much more on the line for a 40-something player - exemptions, momentum going onto the Champions Tour, maintaining a 7-figure lifestyle they've grown accustomed to.
When in doubt, bet on someone over 40.

Regards,
Steve
