Perspectives on the John Deere Classic

Thomas Hawley 0 comment

I love this place!

Entrants ranked on history in the John Deere Classic event. The value reflects the player’s success and number of years competed within the last eight years, weighted in favor of more recent seasons. A value of 1.000 would mean the player appeared every year and won every time. A value of about .715 puts the player in the top 1 percent of all players who have played the event at least once in the last eight seasons, a value of .335 puts a player in the top 10 percent.
