The 2019-20 PGA Tour season concludes on this Labor Day weekend with over $45 million on the table for the remaining 30 golfers taking the course at the Tour Championship from East Lake Golf Club in Atlanta, Georgia

This will be the second year of the staggered start with top players starting farther under par. 

The quartet of Dustin Johnson, Jon Rahm, Justin Thomas and Collin Morikawa has won seven of the last eight events in which at least one of them was entered in the field. They start out at 10 under, 8 under, 7 under and 5 under, respectively, this week and will have a nice head start on nearly everyone in this tournament.

Rory McIlroy, who has two FedEx Cups to his name, will start this week at 3 under, but he might not finish at all. His wife Erica is expecting, and Rory said last week at the BMW Championship that if the baby comes, he's out.

For somebody like Mackenzie Hughes or Lanto Griffin, this week could be a big deal financially. Players like that have a chance to double or triple their career earnings by winning the $15 million first prize. Of course, they aren't likely to come from eight or nine or 10 strokes back. But this week is about far more than just a trophy at the end of it all, especially for less-established players than stars like Jon Rahm and Justin Thomas.

There are some monster names not in attendance this year. Tiger Woods, Brooks Koepka, Jordan Spieth, Rickie Fowler, Adam Scott and Tommy Fleetwood will all be watching from home. But as far as 30-man fields go, this one is great. The fact that the top three players in the world are the top three on the leaderboard make it that much better. 

The No. 1 player in the FedEx Cup standings -- currently Dustin Johnson -- will start at 10 under. Jon Rahm will start at 8 under and so on down the list. The leaderbaord beginning Friday, will look as follows:

10 under -- Dustin Johnson
8 under -- Jon Rahm
7 under -- Justin Thomas
6 under -- Webb Simpson
5 under -- Collin Morikawa
4 under -- Bryson DeChambeau, Sungjae Im, Daniel Berger, Hideki Matsuyama, Harris English
3 under -- Rory McIlroy, Patrick Reed, Brendon Todd, Sebastian Munoz, Xander Schauffele
2 under -- Lanto Griffin, Tyrrell Hatton, Tony Finau, Scottie Scheffler, Joaquin Niemann
1 under -- Abraham Ancer, Kevin Na, Ryan Palmer, Kevin Kisner, Marc Leishman
Even -- Mackenzie Hughes, Billy Horschel, Cameron Champ, Viktor Hovland, Cameron Smith
