Under the current system, any player within the top five entering this week who wins the Tour Championship will also win the FedEx Cup.
Thomas is ranked fifth in the FedEx Cup rankings coming into the TOUR Championship and has a good chance of winning the biggest prize in golf with a solo second finish on Sunday.
PGA Tour commissioner Jay Monahan unveiled a string of changes on Tuesday that go into place next year and are created to simplify the playoff system, ending with the Tour Championship at East Lake Country Club in Atlanta with the $15 million finale.
The top 10 players throughout the regular season will divvy up the $10 million pot with the No. 1 player taking home a $2 million check down to the No. 10 receiving $500,000. FedEx last year agreed to a 10-year extension, and the bonus pool for the postseason now is $60 million (along with $10 million in bonus money for the regular season).
"We're thrilled with these changes put forth today".
"Compared to the current system, the beauty here is in the simplicity", PGA Tour commissioner Jay Monahan said.
"This is a significant and exciting change for the PGA TOUR, our players, our partners and - most importantly - our fans", said Monahan.
The FedExCup Playoffs have been reduced from four to three events beginning next season.
Woods is now 20th in the FedEx Cup point standings, but every golfer in the field could potentially end the season by claiming the FedEx Cup. But starting next year, points will not be reset.

Florence hit North Carolina on 14 September as a category one hurricane travelling at very slow speeds across the eastern US. He then toured a devastated neighborhood in the city of New Bern and also helped distribute food to local residents.
We're quickly nearing the start of the 2018 Tour Championship, the fourth and final event of the FedEx Cup Playoffs.
The next five players will all be tied at 4-under, and every set of five players will be one stroke behind that, ending with Nos. DeChambeau was in control of that event, so Rose figured he did well to win "the other tournament".
Being extremely analytical by nature, Horschel noted that he won the Tour Championship with a score of 11 under and the last two champions won at 12 under.
Also, the model says three golfers with odds of 16-1 or longer will make a deep run at the Tour Championship title.
Most of the usual suspects are here, with the notable exception of Jordan Spieth, who misses the TOUR Championship for the first time in his career. "It's that simple", Monahan said.
FIELD: A decent field here, and Ryder Cup aces Sergio Garcia and Thorbjorn Olesen are the stand-out names for sure, whilst defending champion Lucas Bjerregaard is regarded the favourite.
He added: "You could just be shot out of the tournament really, because if you start nine or 10 back and shoot a couple over the first day your week is realistically done".
The victor is determined by his score to par, not his 72-hole score.
These changes aim to eliminate awkward moments like the one that occurred past year when Xander Schauffele won the Tour Championship but Justin Thomas captured the FedExCup. That part's a little bit of a bummer but we're just going to see how it unfolds and hopefully it turns out well. I liked the way that it is now but, like anything, you're just going to have to get used to it.
