Results of tournaments so far indicate depth on PGA Tour's gotten greater

Europe has the top four players in the world ranking. The strength of the PGA Tour might come from the likes of Mark Wilson, D.A. Points and Aaron Baddeley.

The PGA Tour still has the strongest fields, according to how many ranking points are allocated. Through two months, only twice has a European Tour event offered more points -- Abu Dhabi and Dubai.

Another statistic that might show depth of the PGA Tour comes from its winners.

Seven of the 10 winners were ranked out of the top 100 in the world. The exceptions were Bubba Watson (No. 33 when he won Torrey Pines), Luke Donald (No. 9 when he won the WGC-Accenture Match Play) and Wilson, who was No. 91 when he won the Phoenix Open. Wilson had been No. 237 when he first won this year at the Sony Open.

On the European Tour, all but two of its winners were ranked outside the top 50 -- Thomas Bjorn (No. 134 when he won the Qatar Masters) and Shiv Shankar Prasad Chowrasia (No. 497 when he won the Avantha Masters in India).

“I think the fields are so deep nowadays,” Rory McIlroy said. “And the difference between the top 10 players and the top 200 players … there’s not that much difference. If you lined everyone up on a range, you couldn’t tell the difference, really.”

It could be a case where Europe has strong fields among the top two dozen, while the PGA Tour is strong all the way to the bottom.
